Deterring Chemical War: The Reagan Formula

(Archived document, may contain errors)

272 I June 15, 1983 DETERRING CHEMICAL WAR THE REAGAN FORMULA INTRODUCTION Congress again is debating the Reagan Administration's pro gram to deter chemical warfare by modernizing America's aging and obs olescent inventory of chemical weapons. History teaches that chemical warfare erupts only against weak and unprotected forces incapable of retaliating. To prevent chemical attack, the U.S in World War I1 and after=-has had ready an arsenal prepared to res pond in kind. No longer. In the past decade, America's chemi cal arsenal has grown increasingly we'aker. This the Administra tion is attempting to reverse with a cautious force modernization program.

Fourteen years ago, the United States unilaterally halted production of chemical weapons to pave the way for negotiation of a chemical weapons convention. Yet Moscow responded with an un precedented buildup of chemical warfare forces.

79. Soviet use of chemical agents against Afghan freedom fighters has bee n amply documented and the myco toxins employed by Vietnamese troops in Laos and Cambodia almost certainly are of Soviet rig in The Reagan modernization proposal is a necessary response to the growing threat posed by the Soviet Union. The Administration i s not seeking to match MOSCOW'S offensive capabilities. The modest upgrading of U.S. chemical arsenal, rather, is designed to deter adversaries from using chemical weapons and to lay the groundwork for a complete and verifiable ban on their use.4 BACKGROUN D The Geneva Protocol of 1925 was drafted after the use of chemical weapons in World War I.5 It prohibited the first-use of chemicals but in no way proscribed development or stockpiling of chemical weapons or their use in retaliation. Even though the Unite d States did not ratify the Protocol until 1975, its policy on chemical warfare has always .accorded with the .Protocol, pledging not to use chemical weapons first, while maintaining a defensive and retaliatory capability as a deterrent.

During the 1960s, public concern over the storage, transport disposal, and testing of chemical munitions was sparked by a series of accidents purportedly involving chemical weapons.6 Open-air testing was prohibited by P.L. 91-441, and restrictions Soviet Biological Warfare Activities, Committee Report, Permanent Select Committee on Intelligence, U.S. House of Representatives, June 1980 Use of Chemical Weapons in Asia, Current Policy No. 342, and Chemical Warfare in Southeast Asia and Afghanistan, Special Report No. 98, Marc h 22 1982; Chemical Warfare in Southeast Asia and Afghanistan: An Update Special Report No. 104, November 1982, U.S. Department of State; James A.

Germany initiated the widespread use of chlorine gas and later phosgene at Ypres on the Franco-Belgian border on April 22, 19

15. Relatively crude protection against these respiratory agents soon rendered them useless for offensive operations against protected troops. As a counter to respirators, the Germans then developed and first used Mustard gas, a blistering agent that required total body protection.

Evidence that the death of 2,200 sheep was caused by the Army's testing of VX at Dugway Proving Grounds in Utah is shaky. Joseph D. Douglass Jr Chem5cal Weapons: An Imbalance of Terror," Strategic Review, Vol 10, Summer 1982, pp. 36-47 Remarks of Vice President George Bush at the United Nations Commit3 I were imposed on other chemical weapons activities by P.L. 91-121 in 19

69. Public opposition to chemical weapons was further fueled by the use of riot control agents and defoliants in Vietnam, de spite their questionable military utility.

President Nixon in 1969 unilaterally renounced the use of biological weapons under any circumstances and ordered the de struction of all existing stockpiles. On the same occasion, he reaffirmed the U.S. pledge not to use chemical weapons first and ordered a review of the U.S. chemical deterrent posture. This presidential action, however, was prompted more by the mistaken notion of serious Soviet interest in a ban on chemical and bio logical agents than by expressions of public concern.l At about the same t i me, the Army decided to cease production of unitary chemical munitions so as to defuse the public scare about their alleged environmental hazards. Technical breakthroughs also promised the development of safer weapons that would not pose the risks associa t ed with the storage, maintenance, transport handling under combat conditions, and terminal disposal of unitary munitions. A vigorous research and engineering program established the technical feasiblity of the binary concept.8 1975, the Army requested fun ding for the construction of a binary weapons production facility at the Pine Bluff Arsenal, Arkansas which was denied.

Subsequent funding requests were defeated.g Carter Administration no appropriations/authorizations were re quested. It required a congressional initiative in 1980 to Beginning in During the Ibid p. 43.

Binary chemical weapons are designed with two relatively harmless and nontoxic chemicals. jectile, one chemical is filled and stored in the artillery shell itself.

The other chemical is stored separately and filled into the second chamber of the shell before the projectile is loaded into the gun. The two chemi cals, difluoro and isopropyl alcohol amine, combine in flight to.form GB a nonpersistent nerve agent.

The funding request for the 155mm GB projectile production facility was resubmitted in FY 1976, up to $8.8 million from $5.5 million in FY 1975.

This request was again refused with the argument that one more year should be allowed to determine progress in arms control negotiations on chemical weapons, and the $8.8 million was reprogramed for the procurement of defensive equipment 1977 within the Administration despite strong protests by the Secretary of Defense to continue plans for a production facility with no accompanying commit m e nt to production of June 1977 that no actions would be taken to improve the retaliatory stockpile 1980 budget cycle in the light of progress made in arms control talks with the Soviets In the case of the 155mm GB chemical artillery pro As a result, no bud g et submission was made for FY In FY 1978, this item in the amount of $15.3 million was deleted The Department of the Army was directed in the defense guidance This was in line with President Carters directive This decision was to be reviewed at the beginn ing of the FY 4 provide minimal funding of $3.15 million for the construction of a.binary plant in EY 19

81. The EY 1981 Supplemental request of $20 million for the 155mm.GB-2 projectile plant was also ap proved and funds were appropriated.

Since 1969, th e Department of Defense had maintained only a minimal Chemical Preparedness Program for perfecting defensive equipment against chemical agents and maintaining the existing stockpile of chemical agents. The neglect of the U.S. deterrent capabilities is epi tomized by the Army's attempt to dissolve its Chemical Corps. Funding levels for chemical warfare programs declined steadily during the 1970s, from $145.5 million in 1972 to $111 million in 19

78. Reacting to evidence from the.Yo.m Kippur War of formidable Soviet collective protection capabilities for crews of armed vehicles, Congress, in P.L. 95-79, directed the Army in 1977 to improve its own collective protection systems.

Yet no .additional funds were appropriated for that purpose.

The Reagan Administr ation Approach Upon coming to power, the Administration initiated a long term program designed to remedy the most glaring deficiencies of the present U.S. chemical warfare posture. Growing concern about Soviet chemical warfare capabilities, the increasing l y doubtful adequacy of the U.S. retaliatory posture and persisting lack of sufficient defensive gear, and hardening evidence of .Soviet use of chemical weapons in Afghanistan combined to shape the Reagan Administration's program to enhance the U.S. chemic al warfare preparedness and deterrent posture.ll Funding levels for all chemical warfare related programs increased from $259 million in E'Y 1981 to $532 million in EY 1982 and $705 million in J?Y 19

83. The Administration .is currently requesting close to $1 billion for N 1984 and plans to spend between $4 billion and $6 billion over a five-year period.

Roughly 70 percent of these program funds will be expended for the improvement of protective measures, and some 10 percent have been designated for weapons demilitarization percent of the total chemical warfare budget request is slated for the procurement of new munitions with the remaining 20 percent going toward inventory maintenance and the construction of a production base Only about 10 In 1981, the Reagan Administration won supplementary funding for the binary plant at Pine Bluff, Arkansas, which stop p ed short of actual production of lethal nerve gas agents; this would have required presidential certification of an existing national lo Brad Roberts, Chemical Warfare: Background and Issues, 81081, Congressional Research Service, August 30, 1982 Record, September 10 and 16, 1980.

21. Certification was sub mitted on February 8, 1982, accompanying EY 1983 funding requests of $105 million for the binary nerve gas munitions program 54 million of which was designated for the procurement of 155mm GB2 nerve agent artillery projectiles; it was deleted in conference.

For EY 1984 61 million was originally requested for munitions procurement 43.2 million has be en withdrawn by the Defense Department because of engineering problems on the Navy's Bigeye 500-pound bomb In 1982, the Senate followed the recommendation of the Armed Services Committee and endorsed the President's program after narrowly defeating an ame n dment sponsored by Senator Gary Hart D-Colo to prohibit the $54 million funding, for weapon procure ment and to transfer that funding to the procurement of defensive equipment. Three amendments were added, however, during the floor debate. Two called on t h e President to intensify arms control efforts and the third, sponsored by Senator Mark Hatfield R-Ore circumscribed the scope of the weapons production program by prohibiting munitions procurement in excess of the requirements of the U.S. armed forces, wh e reby effectively reject ing munitions procurement for NATO forces.12 The House did not follow the recommendation of its Armed Services Committee. Instead, it removed the production funds for the 155mm shell from the defense authorization bill. Through Con f erence Committee action, the production funds for the binary weapon were deleted In renewing its efforts to obtain funding for the actual production of binary weapons, the Reagan Administration confronts again the same group of Senators and Congressmen wh o opposed modernization of chemical weapons inventory throughout the 1970s and defeated the funding requests in FY 19

83. Again the debate revolves around two hotly contested issues: the quantity and the quality of Soviet military preparedness for chemical warfare; and the sufficiency of the present U.S. retaliatory systems, especially as it relates to the adequacy of the current chemical weapons stockpile THE SOVIET CHEMICAL WARFARE POSTURE Experts agree that the Soviet Union maintains the most elaborate chemical warfare capabilities of any military forces.

The Soviets have a balanced mix of defensive equipment and offen sive weapons, a military doctrine that integrates chemical war fare operations with the use of conventional and nuclear weapons and thoro ughly train all military personnel in the conduct of combat operations on a contaminated battlefield. Chemical troops l2 Congressional Record, May 6, 13, and 20, 1982. 6 numbering about 85,000 men today, were created as an independent service in 1924 and, subsequently, four chemical schools, several dedicated chemical munitions factories, and some seventy chemical warfare training grounds were established by the Soviet armed forces. Soviet troops train with live chemical munitions at a cost of several doze n fatalities annually.

Soviet military doctrine envisages the offensive use of chemical weapons and frankly acknowledges their combat util ity.13 Soviet chemical warfare doctrine supports massive, sur prise attacks against a broad spectrum of targets rangi ng from the edge of the battlefield to rear areas such as airfields logistic support facilities, and troop concentrations; it also calls for rapid offensive strikes to quickly dislodge IIenemy defenses. In order to suppress resistance of defending forces S oviet strategists plan to exploit the principle of mass and the element of surprise. Chemical weapons are particularly well suited to support offensive operations and, indeed, Soviet planners view .all military capabilities as organically related generati n g a synergistic effect when used in combination fore, it is not unreasonable to surmise that Soviet strategists envision the use of all available military capabilities in order to inflict maximum damage and attain their combat objective There Soviet milit a ry organization and protective equipment are designed to ensure effective combat operation in a contaminated environment. All modern tanks and armored combat vehicles pro vide crews protection against radiological and chemical contamina tion.14 Positively pressurized vehicle interiors together with air filtration systems allow crews to move freely and to operate weapons systems unencumbered by bulky garments, hoods, and gloves that retard combat effectiveness. Other new generation combat vehicles, includin g support vehicles, missile transporters, and launching platforms as well as command vehicles are equipped with supplies of individual protective materials. While these lack certain advantages of collective crew protection systems, they permit the crews to leave their vehicles and to perform combat operations in the surrounding area without prior vehicle decon tamination.

Collective protection systems when combined with extensive decontamination equipment allow Soviet forces to rapidly traverse l3 For a det ailed discussion see Christopher N.

Sovie t forces field several models of decontamination trucks, among them the ARS-12U that is probably the most versatile. It has the capability of decontaminating with chemical solvents twelve battle tanks in rapid order without requiring replenishment.

The TMS -65s decontamination vehicle, first detected with Soviet forces in the mid-l960s, is a truck with a turbojet engine powered spraying device that is said to have the capability of decontaminating the outer surfaces of a tank in less than one minute when op erating in pairs.15 Soviet forces also maintain steam-cleaning equipment, which is somewhat less effective but remains useful in view of Soviet tolerance of considerable levels of contamination.

The heavy emphasis on decontamination equipment indicates tha t Soviet planning. anticipates a significant role for persistent and nonpersistent chemical agents in any future war in Europe or elsewhere. In view of the limited inventory of these agents among NATO forces, it must be concluded that Soviet forces plan t o use them in support of their offensive operations is further substantiated by the virtual inability of NATO forces to sustain combat in a contaminated environment for an extensive This conclusion period of time.16 Soviet forces are also well equipped for decontamination of personnel. The protective gear worn by Soviet soldiers consists of the standard ShM respirator and the ZFK-58 heavy suits of cloth-lined rubber as well as rubberized boots. This gear is inferior to NATO's new vinyl suits which tlbreathe l l through a layer of activated charcoal acting as a chemical filtration system that reducesheat buildup. Heat stress caused by Soviet suits within a short time of wearing forces Soviet soldiers to seek shelter to change their clothing, which is then decon t ami nated and reissued.

Soviet stockpiles contain a great variety of nerve gases, blis tering agents, and toxins. There are also indications of stores of hydrogen cyanide, a blood agent first used in World War I, and some inventory of incapacitating agents.22 C hemical weapons can be delivered by Soviet forces against a broad array of targets. The Soviets are credited in unclassified literature with the capability of delivering chemical munitions with all major tactical weapons systems--missiles, rockets and mul tiple rocket launching systems, bombs, and aerial spray tanks giving them the capability of striking anywhere within NATO.

Despite the Army's intention t o halt production of chemical weapons only temporarily while awaiting the development of binary weapons, the United States has lived with a de facto moratorium on chemical weapons manufacture 'for the pastfourteen years. Owing to inadequate maintenance as well as natural aging of weapons components and chemical agents, the U.S. stockpile has deteriorated dramatically. In effect, 11 per cent of all weaponized chemical agents are unservicable. Most of these are M-55 rockets filled with GB and VX nerve agents as well as 155mm howitzer projectiles U.S. capabilities are further constrained by a mismatch between munitions and available delivery systems. For instance multiple rocket launchers have been withdrawn from active service and the standard l05mm howitzer i s being phased out and currently in use only with a few Marine battalions and two air-mobile divisions. The old 155mm gun is also being replaced by a new extended range howitzer and, while the old 155m munitions are compatible with the replacement, they c annot be fired at its full 22 David C.

Bulk GB nonpersistent nerve gas accounts for 14 percent of the stockpile, last produced in 19

57. Persistent VX nerve gas, last produced in 1967, accounts for 6 percent of bulk agents utility, however, without facilities to fill them into munitions.

No facilities at present are equipped to handle mustard gas. The GB weapons production facility at the Rocky Mountain Arsenal near Denv er, Colorado, has not operated since 1969 and is not being maintained. Extensive and time-consuming renovations would be required to bring the plant back into operation Bulk agents are of no military The militarily attractive VX, a persistent nerve agent of great value for area denial or contamination of enemy logistic facilities, airfields, and command posts, cannot be munitionized as well.

According to congressional testimony25, bulk agents can be used as fill only for a small number of Navy refillable spray tanks for aerial applications of chemical agents.

Because no filling facilities are available, more persistent agents like VX or mustard gas cannot be loaded into bombs which could offer a stop-gap measure to mitigate temporarily the total lack of U.S persistent agent, long-range capabili t y until the binary "big-eyel bomb becomes available VX filled weapons were originally produced at the The same applies to VX loaded into Air Force 23 Theodore S.

Gold, Statement April 7, 1983, op. cit 8. 11 The utility o f significant components of the U.S. chemical weapons stockpile is further diminished by problems associated with their storage, transportation, and handling. Most of the chemical weapons are stored at three locales in the continental United States. Only 1 0 percent are forward deployed to West Germany. In wartime, it would be exceedingly difficult to resup ply the quantities of chemical munitions necessary to force Soviet troops to maintain a protective posture.26 Some of the munitions are leaking and cann ot be handled safely without pro tective equipment which will slow shipping to where they are needed. Furthermore, their reliability is uncertain, posing con siderable risks to U.S. troops using them.

Thus, despite repeated allegations to the much of the nominally impressive stockpile of chemical agents and munitions is militarily useless because it is either undeliver able or antiquated.

The inadequacy of U.S. retaliatory capabilities has been surpass ed only by the glaring deficiencies of its protective posture. Because it has always been the U.S. objective to deter the use of chemical weapons and not to initiate their use, the U.S. military has never devoted sufficient attention to equipping and trai n ing troops to fight and survive a chemical war. Despite efforts in recent years to correct thes'e shortfalls, it is gen erally agreed that U.S. and allied forces are incapable of ac complishing their mission objectives under chemical warfare conditions.28 As the ability to defend effectively against enemy use of chemical warfare is an integral part of a viable deterrence posture, it is rather obvious that the U.S. has never had a truly viable deterrent 26 27 28 According to DOD answers to questioning by Se n ator John Warner (R-Va it will take 40 sorties of C-141 aircraft to move 20,000 rounds of 155mm shells to Europe, a number the army considers sufficient to meet initial battlefield requirements unitary agents because the elaborate safety requirements asso ciated with moving them.

But these attempts suffered from insuff icient funding levels across the entire spectrum of chemical warfare activities.

The Reagan Administration correctly identified improvement of the defensive posture as a policy priority and has initiated major steps to remedy the obvious shortcomings. It p lans to increase the number of chemical warfare specialists in the Army, which had fallen to about 1,600 men in the mid-l970s, to some 10,000 men and 14 chemical defense companies by FY 1985; and it has strongly invigorated training at the recently reopen e d Chemical School at Fort McClellan, Alabama.29 The Air Force, which pioneered the dirty cockpittt concept, will receive funding for the acquisition of enhanced decontamination equipment; and 800 additional defense specialists will be attached to bases in high threat areas, in addition to 707 life support technicians for maintenance of air crew protective equipment.30 The Navy will undertake research on collective crew protection and plans to upgrade its ability to conduct amphibious missions in a chemical warfare environment.

Efforts are also being accelerated to develop a new protective suit that will be flame resistant and reusable and improve the com bat performance of troops wearing protective gear. A new mask is under development which will reduce vis ion obstruction and will be compatible with other equipment, such as night vision devices.

Pursuant to the initial congressional mandate of PL 95-79 to incorporate collective crew protection systems in tracked com bat vehicles, the Army decided in 1978 af ter extensive studies to develop a hybrid system of combined positively pressured vehicle interiors and ventilated facepieces for crews as the optimal pro tection system with the ventilated facepiece and will be retrofitted with the positive pressure syst e m when it becomes available.31 encies despite the introduction of the M256 chemical detection kit and the M8 series of automatic alarms.

While it is quite possible that the Soviets might prefer to limit their operations to the conventio nal level if they thought that would enable them to reach their ob jectives, the use of chemical munitions is clearly being contem plated as a probable contingency.

The overarching objective of Soviet strategy in the NATO In order to context is to quickly disable and overrun the defending forces and to penetrate NATO territory at a rapid pace accomplish this objective, Soviet forces will seek to wear down and cause h i gh rates of attrition in the frontline forces, de bilitate airfields and key points in the chains of command, and to interdict the supply lines of the defender of nuclear weapons, chemical weapons are particularly suitable for these purposes Short of the u se First, in order to deny the Soviets the battlefield advantages associated with a surprise use of chemical munitions, NATO forces must maintain a protective posture at all times. This invariably impedes their ability to mount an effective defense agains t the attacker who can operate wi'thout performance-degrading gear. Thus the threat of chemical warfare alone works to the disadvantage of NATO. Second, a surprise attack with chemical weapons will result in 10 percent immediate casualties and high rates o f attrition resulting from physical exhaustion due to heat-stress, delayed effects of chemical agents, and the likely breakdown of communi cations between the commander and his troops. Troop discipline will also suffer from the psychological stress of figh ting in a contaminated environment.

Third, Soviet commanders can shield the flanks of their ad vancing columns through the application of persistent chemical agents which will deny the defender the terrain from which to stage effective counterattacks. Four th, through deep strikes against rear area targets using a combination of chemical and conventional munitions, the Soviets cannot only disrupt the orderly conduct of supply operations and troop reinforcements but, through the so-called force-multiplier ef f ect cripple the operation of airports, port facilities, and supply depots for a prolonged period of time. A combined chemical conventional raid against airports can significantly extend the time required for runway repairs and can limit the number of sort i es from these airfields. This could prove invaluable in Soviet attempts to secure air superiority in the European theater. Fifth, chemical munitions of the nonpersistent variety are highly attractive for the preparation of drop zones for airborne assaults behind the frontlines. Sixth, the use of chemical munitions in lieu of 15 nuclear weapons will help avoid damage to targets of potential future value, such as airfields, bridges, and industrial facil ities. Seventh, chemical weapons are exceptionally well suited for combat operations in urban areas and, in view of the popu lation density in central Europe, these areas will likely be prime targets for Soviet chemical warfare attacks. Finally chemical munitions filled with persistent agents could easily be u sed to disable NATO's nuclear capabilities by inhibiting their swift relocation or their use against advancing Soviet troops.

The offensive use of chemical weapons is of indisputable military utility to the implementation of Soviet strategic doctrine and a ttainment of its military objectives complicate NATO's mission of arresting a Soviet onslaught with conventional weapons and will likely trigger early recourse to nuclear weapons. Thus, to rely on nuclear deterrence 0.f chemical warfare is completely unre a listic Their use will greatly Contrary to the contention that a retaliatory chemical capa bility does not add to, but may even detract from, NATO's ability to deter the use of chemical warfare, a capability for retalia tion-in-kind is indispensable for su c cessful deterrence of chemical warfare by the Soviet Union. Many European analysts argue that the possession of such a capability will make the use of chemical weapons more likely because it may convince the Soviets of a diminished resolve of NATO countri es to resort to nuclear weapons.

Thus, in their view, increased reliance on chemical weapons to deter a Russian chemical attack could be costly in terms of re ducing NATO's ability to deter the outbreak of war in central Europe.

This 'line of reasoning is premised on the obviously false assumption that chemical weapons are of limited military utility.

Moreover, it fails to recognize that the threat of nuclear esca lation in retaliation to chemical attacks lowers the nuclear threshold and is not credible i n the absence of outright nuclear superiority and given way to parity on the strategic level and Soviet theater nuclear superiority. Hence, such a deterrence posture lacks credibility. Retaliation-in-kind with chemical weapons, on the other hand, is funda m entally de-escalatory because NATO forces will only continue what the other side had already started. The objective is to limit the intensity and duration of chemical war fare by denying the advantages of using chemical warfare NATO's theater nuclear supe r iority has vanished Forcing 34 See, for example, Uwe Nerlich, "Chemical Warfare Policy Alternatives Defensive and Negotiating Options, in David S. Yost (ed.)

Perry Robinson, "Chemical Weapons and Europe", Survival, Vol 24(1), January/February 1982, pp. 9-18. 16 the attacker into a s imilar force-degrading protective posture and inflicting comparable losses and combat conditions will negate most benefits of offensive chemical warfare operations. It should then be beyond doubt that an exclusively defensive posture will be insufficient for deterrence and will not contribute to redressing the asymmetries on the battlefield.

POLICY IMPLICATIONS In their quest to derail the program to improve the U.S chemical deterrent, congressional critics are again basing their opposition on a series of unsubstantiated assertions rather than on a judicious assessment of U.S. capabilities and force require ments.

The Present StockDile is Inademate Critics contend that stockpile deterioration during the U.S moratorium on chemical munitions production has been negligible has been arrested, and is being reversed.

The review here of U.S. retaliatory chemical warfare capa bilities, however, testifies to the severe shortcomings of the U.S. stockpile. First, the stockpile has a poor agent-munitions mix. In parti cular, U.S. forces lack a persistent agent, long range capability which is becoming increasingly important in the context of doctrinal developments envisaging deep-strikes against second-echelon targets. Chemical munitions used in conjunction with termina l ly guided submunitions against rear-area targets such as troop staging areas could become valuable options in the Army's new conventional defense doctrine known as "Airland Battle 2000l Second, there is a growing mismatch between the munitions stockpile a nd delivery vehicles in service with U.S. and allied forces.

A distinction must also be drawn between tons of chemical agents and tons of chemical munitions in the stockpile. The former is a rather crude measure of the size of the stockpile because it fail s to differentiate between agents stored in bulk form and agents filled into weapons. The other measure grossly distorts the size of the stockpile because it measures the total weight of munitions rather than their content of active agents.

Opponents of f orce modernization tend to use both measurements so as to emphasize the vastness of the existing stockpile even though only a fraction of it retains a residual military utility foes of force modernization fail to appreciate sufficiently the logistic and s a fety problems associated with unitary chemical munitions Finally The Shortcominqs of Binary Weapons are Exaqgerated Critics charge that binary weapons are of questionable military utility because engineering problems have introduced 17 operational .uncert a inties and the binary concept imposes inherent limitations on their use.35 The operational shortcomings of binary weapons that are said to militate against their effectiveness have been vastly over stated and appear large only when no consideration is giv e n to the problems associated with unitary agents. These require elaborate safety precautions in transit and handling on the battlefield. They are also highly vulnerable to Soviet air strikes when stored in unhardened supply depots on the battle field expo s ing troops to undue risks. Most chemical munitions in current inventory are also of limited military utility owing to their short range and suboptimal agent mix. The lack of longer range systems limits'the ability of the armed forces to fully capitalize o n the so-called force multiplier effect.achieved through the combined use of conventional and, preferably, per sistent chemical agents against enemy airfields, supply and communications installations, and staging areas.36 Finally, the detractors of binary w eapons neglect the sub stantial advantages of binary weapons when it comes to their demilitarization. Unitary chemical munitions are extremely difficult and costly to demunitionize. Over the past several years, the Army has gained limited experience with t he disposal of current stocks, demilitarizing some 13,000 munitions at one small pilot plant. Anticipated costs for the disposal of the entire weapons stockpile range up to 3 billion in constant J?Y 1982 dollars. By contrast, the binary weapons are easy t o dis assemble because they contain no lethal components and, as a result, can be disposed of at negligible costs and environmental risks.

Chemical Munitions Are Weapons of Mass-Destruction This proposition is usually invoked by those who seek to play on p ublic fear of the horrors of war and attempt to liken chemical weapons to nuclear weapons. The effects, however, are in no way comparable, be it in terms of their destructiveness persistence or possible. protection against them. While nuclear weapons tend to erase the distinction between combatants and non-combatants, the greater vulnerability of civilian populations than of well protected troops is not an intrinsic feature of 35 GAO report, op. cit., pp. 68-72; Walter Pincus, "Pentagon Finds Unexpected Da nger in 'Bigeye' Bomb", op. cit Ed Bethune (R.-Ark Chemical and Bio logical Weapons Found Inefficient and Unsafe," Congressional Record, May 10 19

83. As one of the most articulate critics of the binary weapons program the Congressman should be aware that the U.S. terminated its biological weapons activities in 1969 and, subsequently, destroyed existing stock piles.

Furthermore, insufficient retaliatory chemical warfare capa bilities will ensure that this civilian vulnerability will remain entirely one-sided. The lack of a chemical warfare deterrent will diminish Sovi et incentives to refrain from the use of chemical weapons and to conclude a comprehensive and verifiable ban.

Western European Views Are Not Determinative While it is correct that considerable reservations exist among Europeans concerning the modernizatio n of the retaliatory stockpile and, indeed, the need for its very existence, it is pointless to predict European reactions to a start of U.S. binary munitions production. The relentless Soviet build-up of military capabilities may well engender a hearteni ng reconsideration of NATO's force posture requirements which could result in a decision of NATO councils similar to the two-track decision on Intermediate Nuclear Force deployment.

More to the point, however, the entire argument about Euro pean unwillingn ess to accept deployment of new chemical munitions on their soil neither detracts from nor negates the need for U.S chemical stockpile modernization. Soviet use of chemical warfare in Afghanistan provides a vivid illustration that theaters .for chemical w a rfare exist outside Europe, for instance in the Persian Gulf and Southern Africa, where the United States must be prepared to deter and, if necessary, to effectively fight a chemical war. It is a display of false deference to allied judgment to allow NATO councils to determine U.S. chemical warfare requirements for other theaters. It epitomizes the pervasiveness of a Eurocentric myopia.

Arms Control Can Eliminate Urqent Policy Decision Opponents of binary weapons production have been arguing for over a dec ade that a verifiable ban on chemical weapons could absolve the U.S. from the need to modernize its chemical munitions stockpile plicate verification and, hence, obstruct a successful conclusion of an arms control agreement. Whether binary stockpiles will hamper verification has not been conclusively established. But it is becoming obvious that the U.S. unilateral moratorium on chemical weapons production has not induced the Soviet Union to exercise similar restraint or to be more forthcoming on the critic a l issues of verification and compliance. At the same time, it has become equally obvious that any agreement without adequate provisions for on-site inspection will be profoundly flawed tions of the 1972 Biological Warfare Treaty which contains no pro- vis i ons for verification. The fact that a ban on biological weapons could be reached within a short period of time in the UN Conference of the Committee on Disarmament is less an indication of the They contend moreover that binary weapons would com This is co n tinuously being underscored by Soviet viola 19 universal aspiration to see these weapons banned than of.the lack of U.S. concern with adequate verification. For more than ten years however, attempts to reach a ban on chemical weapons.have been stalled by Soviet refusals to permit on-site inspections by international teams of arms control experts.

Since the mid-l970s, the U.S. and the Soviet Union have held exploratory talks and 12 formal negotiating rounds on a common draft for a ban on chemical weapons wh ich produced a joint pro gress report for consideration by the UN Committee on Disarmament CD) in July 19

80. The report detailed the scope of the proposed ban, the time-frame envisaged for its implementation, and some provisions on treaty compliance but skirted fundamental questions of verification In January 1981 the Reagan Administration decided to discon tinue bilateral negotiations with the Soviets and to concentrate its efforts on the Chemical Weapons Working Group of the U.N.

Committee on Disarmame nt. This decision was inasmuch an indica tion of U.S. frustration with persistent Soviet refusals to seriously consider and accept genuinely effective verification and compliance procedures as it stemmed from the desire to expose lagging Soviet cooperatio n within the multilateral Working Group.

It also served the purpose of putting pressure.on the Soviet Union with support from non-aligned member countries to accept the U.S. position on verification in light of the unresolved questions surrounding the myst erious release of anthrax at Sverdlovsk and the detection of mycotoxins in Southeast Asia In June 1982, at the United Nations Special Session on Dis armament, Soviet Foreign Minister Gromyko presented a draft paper containing indications of a possible shi f t in the Soviet position on verification hailed by arms control enthusiasts as a further sign of incipient Soviet willingness to compromise on verification and to reconsider its sine qua non, on-site inspection. Judging from Soviet behavior since issuing t his carefully crafted pronouncement, it has been targeted more at the Western arms control community to raise its hope for an agreement and foster opposition to a resumption of U.S. chemical weapons production than it is reflecting a change in the Soviet n egotiating position. It appears as if the Soviets are again succeeding in the present budget cycle in fueling the aspirations of the arms control advocates in Congress This oblique allusion by Gromyko has been POLICY RECOMMENDATIONS The Reagan Administrat i on has charted a balanced course for urgently needed improvements of the U.S. chemical deterrent. It has identified critical deficiencies in the U.S. chemical warfare posture and has proposed a number of interrelated steps that re quire expeditious implem entation 1. Accelerated procurement of protective gear for individual protection and acquisition of wartime reserves 2 3 4 5 6 7 8 9 20 High priority RDT&E of advanced defensive equipment and decontamination devices.

Development of collective protection systems for combat vehicles and command posts and retrofitting of existing equipment.

Improvement of combat training and specialized training for chemical warfare.

Increased manpower assigned to chemical warfare tasks.

Greater efforts to conceptualize chemical warfare scenarios to identify hardware requirements, and to refine doctrinal guidance for weapons use and individual combat performance.

Improved maintenance of existing chemical stockpiles and demilitarization of obsolete, unsafe, and unservicable munitions.

Establishment of a production base for the I1bigeyelf spray bomb and engineering efforts to solve remaining operational problems.

Start-up of small-scale production of the 155mm binary shell components in preparation of final assembly.

Furthermore, the Administration should pursue the following ini tiatives 1. Explore the engineering feasibility and military usefulness of chemical su bmunitions for use against rear-area targets 2 3 RDT&E of a chemical warhead filled with persistent VX for deployment on Ground Launched Cruise Missiles.

Re-examination of naval shipbuilding programs with respect to changes in hull-engineering designs for the purpose of creating a collective protection capability for crews of naval vessels 4. Hardening of critical command and communications stations On the foreign policy level the Administration should persist in its efforts to reach a comprehensive and v e rifiable ban on chemical weapons in Geneva. Simultaneously, it should begin to forge a consensus on the need to modernize the chemical stockpile in the absence of concrete results at the negotiating table by publicizing in stark terms Soviet chemical warf a re capabilities and the need to deter their use through a viable countervailing deterrent. As part of this effort, the Administration should also step up consultations with the European NATO allies to reach agreement on the desirablilty of strengthening d eterrence.by raising the against chemical contamination. 21 nuclear threshold through the deployment of modern chemical munitions in adequate numbers as a deterrent against chemical warfare.

CONCLUSION The United States unilateral moratorium on chemical we apons production over the past 14 years has brought U.S. ability to respond to a chemical attack to a dangerous low. As a result the U.S. now is at a crossroads. Continued procrastination and indecision on modernizing its chemical arsenal will further ero de America's ability to deter chemical aggression. Ronald Reagan's cautious program is designed to reverse this dangerous trend.

Equally important, the Reagan formula will provide a solid basis and incentive for negotiating a verifiable ban on chemical weapons.

Until such a ban is concluded, however, the U.S. must be able to deter a chemical attack. The battlefields of Afghanistan and Southeast Asia prove that Moscow regards chemicals as an acceptable and useful weapon. The U.S. must take the steps to make chemicals unacceptable.

Manfred R. Hamm Policy Analyst 37 Congress recently appropriated funds for the MX missle in support of the President's two-pronged strategy for arms control negotiations on stra tegic nuclear weapons. Congress should allow the Adm inistration to pursue a similar parallel policy on chemical weapons.
