267 May 17, 1983 SHORTCHANGING. MILITARY READINESS INTRODUCTION U.S. armed forces must be ready to fight if they are to constitute a credible deterrent and an effective tool for defend ing national interests. Weapons must be operational, manpower well t rained, and units well stocked with ammunition, spare parts, fuel, and support equipment for sustained combat. Yet readiness is a weak link in U.S. defenses.

For a number of reasons, including deep congressional defense budget cuts in the 197Osl and Penta gon budget strategies shortchang ing readiness in favor of new weapons, U.S. readiness for sustained combat degenerated to alarmingly low levels from 1975 to 1980.

In 1980, less than 40 percent of all divisions, air squadrons and ships were rated fully or substantially combat ready. In the past few years, the state of readiness has improved in.many areas with increased funding in the last Carter defense budget and all the Reagan budgets.2 were rated fully or substantially ready.

In 1982, 51 percent of all combat units During the 1970s, Congress cut a total of $83 billion from Administration budget requests, which were inadequate in the first place to sustain U.S armed forces at a "steady state" level of force structure and readiness.

Both consequently declined N.B Readiness, in this.paper, is discussed in terms of conventional forces only.

The Defense Department reports that readiness funding increased in real terms by 8.9 percent in FY1981, 8.3 percent in FY1982 and 2.7 percent in FY19

83. The FY1984 budget contains an increase of 10.2 percent for readiness.

Funding for readiness items falls under a number of appropriations cate gories There is no readiness account per se in the defense budget. 2 America's armed forces, however, are still not sufficient ly prepared to engage in sustained combat; the prospect for genuine, steady readiness improvement in the near future, moreover, is bleak There is not enough money in the Administration's defense budgets to fund adequately all the force expansion, moderniz a tion and readiness programs contained in the Services' EY1984-1988 plans, and readiness is losing out to other budget items. On top of this, Congress is cutting deeply into the Administration's rhetoric that readiness programs are !'off limits" to cuts. b u dget requests, even directly into readiness programs, despite By cutting readiness funding, Congress is creating a serious imbalance in funding for readiness and moderni~ation,~ which will result in severe readiness deficiencies in the later 1980s remini scent of the late 1970s To correct the imbalance, however force modernization must not be scaled back, as some members of Congress unwisely have urged, but more funds must be spent on readiness.

READINESS AS A KEY ELEMENT OF MILITARY CAPABILITY In the last ten years, the United States has fallen dangerously behind the Soviet Union in military capability tial U.S. military buildup, the USSR's margin of superiority could force the U.S. and its allies to back down in the face of a Soviet challenge or suffer a humiliating military defkat ensure high confidence in its military capability to defend national interests, the United States needs to modernize its forces with effective weapons and to expand its force structure in several areas. Yet even if U.S. units h ave the most modern weapons, it will mean little if these weapons do not work or if combat supplies run out hefore the battle is won Without a substan- To U.S. forces must be ready for war on short notice.

Posture Statement of the Joint Chiefs of Staff warns, for example that the Warsaw Pact could launch a surprise attack "after having been heavily reinforced, in a matter of weeks, from the USSR.Il Some analysts believe that NATO could have as little as two days' warning of attack. The U.S., therefore, cannot rely on a lengthy period of ttstrategictt warning during which it could expand its force structure and enhance readiness. A major war with the USSR is likely to'be a 'Icome as you are" affair The FY1979 From N1975 to FY1980, a period of severe readiness shortfalls, spending for Operations and Maintenance (OM a rough indicator of readiness spending, exceeded spending for Procurement, roughly equivalent to force modernization, by an average of 20 percent b u ildup, procurement spending surpassed OM spending in FY1982 and will continue to grow at a faster pace, exceeding OM spending by 31 percent in FY1986 During the Reagan defense 3 This also means that the United States must have on hand all the materiel and troops it needs to defeat Soviet or other aggres- sion until U.S. industry can be mobilized for a longer war effort. During the 1970s, U.S. military staffs assumed that war in Europe would last no more than 30 days. reserve supplies for even this modest r e quirement. The Reagan Administration more prudently is estimating a longer war. The most recent defense Consolidated Guidance directs the Defense Department to earmark enough funds over the next five years for supplies to support 60 days of combat Congres s failed to provide the DISTRIBUTION OF FORCE READINESS Some analysts question whether the United States needs to maintain all forces at the same levels of readiness, They point to the fact that the Soviet Union keeps only a small portion of its forces at h igh readine~s This is hardly comforting, however, since Soviet numerical superiority is so great that, even with proportionally fewer high readiness units, the USSR still has many more ready forces than the West. Because Soviet ready forces are equipped w ith good quality weapons and would have the advantage of strategic initiative, they are a serious military threat to Europe and Southwest Asia.

Quality U.S. weapons compensate somewhat for the fact that the United States maintains a much smaller force stru cture for most types of units than does the Soviet Union. But in order to to have a good chance of blunting Soviet aggression, the U.S. must keep a very high percentage of its forces at high readiness. According to former Defense Secretary Melvin R. Laird , the U.S llshould have an absolute minimum of 70 percent of its units combat ready at all times."5 Today, the U.S. maintains about 30 percent of Army divisions 25-30 percent of naval forces, and 54 percent of tactical fighter For example, out of a total o f 185 divisions in the Soviet Army Order of Battle only 70 are maintained at a Category I readiness level (i.e units have 75-110 percent of their assault strength in both men and equipment 55 divisions are maintained at a Category I1 level (manned at 50-70 percent strength, with equipment close to full strength but most in storage); 60 divisions are maintained at the Category I11 level (manned at 10-33 percent with only 33-50 percent of required equipment, most of which is in storage). While Category I divi sions are immediately deploy able, Category XI divisions need 30 days of preparation before they would be combat ready and Category I11 divisions are not deployable until between 90 and 120 days after mobilization.

Isby, Wea ons and The Problem of Military Readiness (Washington, D.C American Enterprise Institute, 1980), p. 21. 4 attack wings deployed overseas as the first line of defense against Soviet attack. U.S. policy has been to keep these forces at a relatively high readiness level. Forward deployed forces however, by themselves cannot beat back Soviet attacks in Europe or South Asia.

Hence, most active U.S.-based units must be ready to be deployed quickly overseas to ser ve as reinforcements or in the case of South Asia, as the major intervention force. U.S. air and sea transports are so meager that it would take 30 days to move only one mechanized Army divison to the Persian Gulf area if all available airlift capacity we r e used. This does not mean, however, that the United States can be complacent about the readiness of U.S.=based units. The proper response to U.S. lift deficiencies is not to cut back on force readiness but to buy the necessary lift resources to support U . S. military strategy the nation's military plans. For example, four-fifths of the Navy's minesweeper force belongs to the Naval Reserve Fleet. The Army Reserve supplies over two-thirds of the combat service support units (transportation, fuel supply, main t enance, etc and a number of combat maneuver units for ''filling out" divisions forward deployed in Europe. The Individual Ready Reserve (IRR) supplies -individual replacements for combat losses in active units. One third of all Air Force fighter wing equi v alents are National Guard or Reserve units. units are highly proficient-in some cases more so than active units-and should be maintained at relatively high readiness levels to augment active force deployments U.S. Reserveflational Guard forces play critic a l roles in Many National Guardmeserve PROBLEMS IN FORCE READINESS A ready force meets these four criteria 1) its weapons and equipment are in good working order and can be maintained in good working order during peacetime to support training require ments and during war to support combat mission requests 2) it is well stocked with the necessary combat and support equipment to fight long enough to prevail 3) it is manned with adequate numbers of personnel to use weapons effectively; and (4) its personnel ar e well trained, led, and motivated.6 Are U.S. armed forces ready?

With the increased funding for materiel readiness approved during the final year of the Carter Administration and the first Force readiness (the capability of a force to perform its assigned mission promptly) and force sustainability (the staying power of a force) are often distinguished. of the same general capability to sustain military operations, with readiness" measuring pre-D-Day status, extending at most into the first few days of com b at;and "sustainability" measuring post-D-Day staying power, or "readiness in combat They can, however, be considered merely two aspects 5 two years of the Reagan Administration, the capability of the armed forces to maintain weapons operationally ready ha s been improving. The average mission capability rate for Air Force tactical fighter/attack aircraft has increased from 62 percent in N1980 to 66 percent in 1982, at a time when flying hours are also increasing, thereby causing more wear and tear on equipm ent. The Navy's mission capability rate for its fighter/attack planes has risen from 53 percent in FY1980 to 56 percent in N1982.

The Services are not out of the woods, however. Mission capability rates for some weapons are still below acceptable readiness levels while in some areas readiness has declined. Example: The materiel readiness of major naval combatants submarines, aircraft carriers, and battle group escorts--measured in terms of Command Operationally Ready (COR) rates, dropped from an average of 71 percent in N1981 to 67 percent in FY1982.

Stocks of spare parts, vital to keep weapons and equipment operational, remain inadequate even with increased funding Refer to the Appendix for a checklist of the costs of selected readiness items.) One problem is that requirements for peacetime operating spare parts (POS) are understated. Combat units do not train enough with their equipment. As training time increases, as it should, spare parts will be consumed at a higher rate. Requirements for war reserve s pares are also inadequate to support the intensity of operations in war. Air Force General Wilbur L.

Creech, Commander of Tactical Air Command, for example, has reported that "The wartime needs of our theater commanders suggest sustained [sortie] rates wel l in excess of the sortie levels the WRSKs [War Readiness Spare Kits] are currently designed to provide.lI8 insufficient to fund even the inadequate stock levels set by the Services. Spare parts producers, many of which are sole source suppliers, are rais i ng the prices of their items just as the Services are.trying to control weapons prices. The programming and budgeting process for spare parts, which must contend with the long lead time in planning spare parts requests and unreliable data on system failur e s, has continuously underestimated spare parts costs.s progress in eliminating the huge shortfall of wartime spare parts, which amounted to. over $1.4 billion for the Air Force alone in EY1981, since the Services generally fund POS first to maintain peace t ime operations Another problem is that budgets in the Five Year Plan are Funding shortfalls for peacetime spares are impeding To be rated C-1 (fully combat ready), at least 75 percent of aircraft and 90 percent of other major equipment must be fully missi on capable. To be rated C-2 (substantially combat ready with only minor deficiencies at least 60 percent of aircraft and 70 percent of other major equipment must be fully mission capable.

All the Services are intro ducing new generations of weapons, many of which are far more technologically complex than their predecessors. Though some of these weapons are designed for system reliability and eas e of maintenance, the evidence so far is that it will cost more to maintain many of these new weapons at a constant readiness level than in the case of present systems.1 It is uncertain how much funding is needed to maintain the Services' new weapons at ac c eptable readiness levels. Many analysts, however, believe that the Pentagon has significantly underestimated requirements for operations and support of new equipment. According to the Conqressional Budget Office, for example, the support costs to maintain a battalion of the new M-1 tanks will be 41 percent higher than for a battalion of MI-60A1 tanks be 59 percent higher than for the M-113 armored personnel carrier.

The Army estimates the increase as 17 percent and 23 percent respectively. If CBO analysts are correct, the Army will face a shortfall in readiness funds for these two systems alone of $1.5 billion over the 1983-1987 period.ll Not all materiel readiness problems can be solved with more money, however. Ironically, the Army and Navy may be doing m ore harm than good by overhauling major weapon systems and components on a scheduled basis one-half of support costs for ships. Yet they actually degrade readiness until all the llbugslv itr~zhd-a typically nine to successfully byxomercial airlines, would be to leave components untouched except for routine maintenance until Itobjective signs of failure" appear Support costs for the new Bradley fighting vehicle will Major overhauls are expensive-constituting fifteen months for naval -vessels A better- pract ice, followed Shortages in Equipment Inventories Adequate maintenance of equipment is not the only problem the Services face combat and support equipment relative to authorized unit objectives and war reserve requirements.

Yet there are severe shortages in these essential Ilcombat sustainabil- ityi1 items. Today, the Services have on hand only 42 percent of their necessary combat sustainability items and only 59 percent of their requirement for petroleum derivatives (fuel, oil, and lubricants Most worrisome, however, is the ammunition shortage. In 1980, the Servic es were short $20 billion in ammunition just to meet a 30-day war reserve level. tration is qequesting $11.2 billion for ammunition, almost three times the outlays of EY19

81. But because the Administration has substantially increased the requirement for w ar reserve materiel in response to a longer war strategy, the U.S. today has only 40 percent of its ammunition requirement on hand and only 39 percent of its tactical missiles. Even with full funding of the Reagan defense budgets, the United States will s t ill fall short of wartime requirements by 21 percent in ammunition and 30 percent in missiles For FY1984, the Reagan Adminis The real shortage of ammunition may be even greater. Assump- tions,about weapons effectiveness tend to be optimistic; this is espe c ially true of guided missiles and llsmartll munitions. Vulner- abilities of the logistics and support infrastructure are often ignored or downplayed.

Stocks of war reserve materiel must reflect this fact The Soviets have hundreds of deep interdic Installations The condition of U.S. operating bases and support facilities overseas plays a crucial role in force readiness. Congress, regrettably, has routinely slashed the Pentagon's request for overseas facility improvements. Several programs, however, are critical for enhanced force readiness overseas and should be fully funded. Among them Family Housing in Europe: "The lack of famil y housing [in Europe] is one of the principal reaons for problems of morale, readiness, and retention Robert Stone, Deputy Secretary of Defense for Installations, has reported. Many married GIs sent to Europe must wait six months to a year before their fam i lies can join them. The emotional and financial hardships resulting from these enforced family separations erode morale and prompt many enlisted persons and senior noncommissioned officers (NCOs) to choose shorter, unaccompanied tours causing readiness an d training problems.

Without such help, the required.personne1 would have to be transported from the U.S. much later than Germa n reservists and at greater cost. Congress failed to authorize FY1983 funds for America's share of the program These would be deployed PERSONNEL READINESS Perhaps the most criticial dimension of military capability is personnel readiness--the numbers and q uality of U.S. servicemen.

Poor living conditions, frequent transfers from unit to unit, boredom, too much time spent on activities unrelated to military combat, among other things, have encouraged many Americans to "retiret1 early from a c tive duty.

The Services have not always maintained high standards in this area. For example, fighter pilots should fly at least 16 hours a month; in 1980, they were flying ten. The Reagan budgets are funding more flying time. In EY1983, Tactical Air Command pilo ts will average roughly 17.5 flying hours a month. The Administra- tion's program goal for FY1984 is 20 hours a month.

Though an improvement, the figures need to be put into perspective. In the first place, 20 hours a month is significantly less than the 2 6 to 27 hours that pilots flew ten and fifteen l4 l5 Caspar W. Weinberger, Department of Defense, Annual Report FY1984, p. 93.

Soviet pilots may fly only 10' hours a mon th, but U.S aircrews have to be better--much better--than Soviet aircrews to offset the great Soviet advantage in numbers of warplanes and ground forces between 25 to 30 hours and 35 to 40 sorties per month The average Israeli fighter pilot tries to fly T h e Navy, to save money for its force modernization and expansion program, has decided to cut back on training time average flying time per month for Navy pilots will decline in FY 1984 from 24 to 20 hours. Navy pilots need more training to maintain profici ency in operating aircraft from carrier decks.

Because of budgeting constraints and program priorities favoring force expansion, the Navy will also reduce its days at sea from 29 to 25 per quarter The It is difficult to determine the optimal training time for. pilots, sailors, tank gunners, or other combat troops. More important than simply numbers of flying hours, days at sea, or field days is the quality of training during those periods. One day at sea for a ship during wuch all weapons are fired against targets realistically, simulating a complex, coordinated enemy attack is many time.s more valuable than a week's worth of routine drill and maneuvers While drills form an integral part of military training equally, if not more, important are exercises in w hich the forces, learn to use weapons in realistic combat environments. The Services have made impressive strides in recent years to improve training realism. The Army, Air Force, and Naval air arms, for example, operate training facilities, where U.S. un i ts confront IrenemyIt forces employing Soviet style tactics and engage in live fire exercises These "Red Flag training exercises, however, are expensive They repire extensive area for maneuvering and weapons firing, sophisticated targets, simulated battle field conditions, great quantities 6f fuel and ammunition, and transportation to move the Army and Air Force each have just one Red Flag facility, only a few units a year can participate.

Current target drones f l y straight predictable courses. It is also vital that U.S. combat personnel have frequent opportunities to fire their weapons in "live fire exercises. Most American weapons crews, particularly those operating systems firing sophisticated smart munitions d o not do so enough, mainly because of a shortage of training ammunition.

Enhancing military skills, however, is not just a p roblem of providing sufficient funds. The U.S. could find itself at war on short notice in a situation for which no contingency plans had been prepared. The armed forces need both Itno noticelf and "short notice" staff planning and field exercise to prepa r e them for this very real possibility. Since a force well trained lfby the bookll may not be militarily effective, because tactics are faulty, the U.S. armed forcesmeed to conduct "free playi1 exercises in which opposing forces can experiment with new tac tics.
