The Adversaries
The Republican Guard
On August 3, 1990, the Iraqi armed forces conducted an overwhelming combined arms assault on Kuwait. Iraqi ground units penetrated deep into Kuwait, reaching Kuwait City in less than five hours. The Kuwaiti armed forces collapsed, the government fled to Saudi Arabia, and the country was completely overrun within two days.
The Iraqi units that conducted the assault were divisions of Iraq's Republican Guard Forces Command (RGFC). The ground attack was spearheaded by Iraq's most capable combat formations: the Hammurabi and Medinah armored divisions and the Tawakalna mechanized infantry division. Three heliborne brigades of the RGFC Special Forces division supported the armored onslaught with a vertical envelopment south of Kuwait City. Behind the lead divisions, four Republican Guard infantry divisions were committed to mop-up remaining Kuwaiti resistance.
The Republican Guard's utility as a military force is evident in its origins, equipment, functions, and doctrine. The RGFC began as a brigade-sized praetorian guard formed shortly after Saddam Hussein's 1968 coup. The unit was formed by combining the most loyal Baathists serving in the Iraqi Army and was sustained by recruits from Saddam Hussein's hometown of Tikrit. Although not used in the September 1980 invasion of Iran, the Republican Guard was committed to the bloody battle for Khorramshahr in October and thereafter saw intermittent action as a "fire brigade" along the southern front. By 1986, the Republican Guards had expanded to five brigades, the bulk of which were committed to an ill-fated counterattack on the Al-Faw peninsula. This Iraqi defeat has been convincingly described as the turning point of the Iran-Iraq war, the catalyst for a shift from the static defensive strategy to an offensive strategy that would ultimately end the war. Guard recruiting was expanded to include previously-deferred university students, and Guard formations soon grew to twenty-five brigades. These units were extensively trained in offensive combined arms tactics, signifying a major departure from the static-defensive mindset gripping the rest of the Iraqi army. Committed to a series of well-planned, set-piece offensives from April to August of 1988, these Republican Guard formations quickly swept away depleted Iranian formations, helping to bring decision to long-stalemated battlefields and a brief peace to the northern Persian Gulf.
The Republican Guard formations were equipped with Iraq's best and most modern equipment. While regular heavy divisions were primarily equipped with obsolescent T-55, type 59, and T-62 tanks, Guard heavy divisions were equipped with the "well-known and very capable" T-72. Reflecting their offensive and mobile orientation, RGFC heavy divisions were equipped with modern Soviet built self-propelled artillery in addition to towed weapons that equipped the remainder of the Iraqi Army. Air defense artillery units assigned to Guard divisions were more robust than regular army units, as some operated radar-guided SA-6 batteries in addition to the normal infrared-guided SAMs and anti-aircraft artillery systems. Additionally, the RGFC maintained an independent supply system and enjoyed priority for all supplies.
Western impressions of the Republican Guard were shaped by its offensive role in 1988, its elevated reputation, and robust tables of organization and equipment. Rightly acknowledged as Iraq's best troops, many writers have found it easy to overestimate the abilities of the Republican Guard. Analogies have been made in U.S. military writings between the RGFC and Napoleon's Old Guard, or Hitler's politico-military elite, the Waffen SS. Oft-touted as an elite force hardened by years of battle, proud of the "fire brigade" role, "possessing excellent reactive abilities," and "the world's most seasoned [troops] in carrying out assaults preceded by chemical attack," Guard formations gained a fearsome reputation. Indeed, when compared to the armed forces of Iraq's neighbors, the Republican Guard was the most powerful military organization in the Persian Gulf region.
An evaluation of the Republican Guard must be balanced by an examination of Iraqi military doctrine, which reveals major shortcomings. Despite the Guard's offensive successes of 1988 and 1990, some important limitations have been illuminated by several authors. Republican Guard tactical successes were largely set-piece affairs, hinging on extensive planning, logistics stockpiling, and rehearsals. After 1987, all Guard offensives were conducted against vastly weaker forces: Iranian formations encountered in 1988 were debilitated by the failed Karballa offensives of 1987 and collapsing civilian morale. Kuwaiti armed forces were taken by surprise in 1990, only one brigade of which opposed the RGFC as the bulk of the Kuwaiti forces were over-run in garrison. Republican Guard tactical doctrine was probably strongly shaped by (if not identical to) regular army tactical doctrine. The only significant tank battle the Iraqis fought was a static defense against a grossly mis-handled Iranian armored division in January 1981. The Iranian division blundered into an Iraqi anti-tank kill zone piecemeal (over the period of three days) and was obliterated. An excellent analysis by Colonel Wallace Franz (USA, Ret.) further emphasized the likelihood of a static Iraqi strategy because the army had been molded by its eight years of fighting a "war of position, tied to fortifications, communications nets, against a low-tech enemy." Iraqi officers were inexperienced at handling large mechanized formations in mobile operations and would be unable to "think rapidly" or "improvise in the heat of battle" due to Iraqi political preferences for loyalty over independent thought or initiative.
Despite doctrinal shortcomings, Republican Guards were the most potent and best equipped units in the Iraqi Army, marking them as an important operational center of gravity in the campaign to liberate Kuwait. As the offensive arm of the Iraqi Army and the most potent military force in the region, the Republican Guards were also a strategic center of gravity, a powerful military instrument of coercion or decision. The Republican Guards also played an important political role. Guard units were the most overt element of the Baath Party's control over the country. The superior equipment operated by the Republican Guard units ensured that they would be well equipped to defeat potentially rebellious Regular Army units. An RGFC mechanized division was stationed in Baghdad throughout the Gulf War, a visible and powerful deterrent to potential mutineers. Additionally, four RGFC infantry divisions, not committed to the KTO, were formed during the war to provide internal security. Guard units were believed to have been involved in the suppression of dissent before the Gulf War, and surviving elements were reported to have participated in the suppression of the Shia and Kurdish revolts after the war. Top U.S. military commanders, Powell and Schwarzkopf correctly perceived the Republican Guards as operational and strategic centers of gravity, forming perceptions that profoundly affected U.S. planning.
Although there were seven Republican Guard divisions deployed in the KTO, the three Guard heavy divisions that spearheaded the Kuwait invasion captured the interest of the theater CINC. These three divisions were emplaced along the Kuwait-Iraq border as a theater reserve. The remaining four divisions were infantry formations entrenched in an east-west line between the heavy units and the Euphrates River.
The Guard divisions used the five-month lull between the invasion of Kuwait and the coalition counteroffensive to prepare vast defensive positions. The units were widely dispersed and deeply entrenched. Engineers prepared thousands of horseshoe-shaped berms to protect individual vehicles. Personnel were protected by shallow five- to ten-man bunkers. Units were stocked with up to thirty days of provisions, and the Guard Corps straddled a huge fortified corps-sized depot and logistics area.
Iraqi intentions for the use of the RGFC were unclear to Coalition commanders. Once the threat of an invasion of Saudi Arabia subsided, it was widely believed the Republican Guard divisions would be held in reserve and then committed to repulse Coalition ground units depleted by battles with the first and second Iraqi echelons. This mission--counterattack--would be similar to much of the Guard's experience in the Iran-Iraq War; heavy air attack, however, would be a new experience for a force that had always enjoyed air superiority.
The United States Air Force
The USAF waged an intense air-to-ground battle against the Republican Guards for forty-three days; its ability to conduct this battle was shaped by pre-war doctrine, training, and equipment. Doctrine provided the basis for many USAF weapons system acquisitions and, within the context of the European NATO-Warsaw Pact scenario, shaped Air Force tactics throughout the 1980s.
"The [U.S.] Air Force has articulated aerospace doctrine at different levels and depths of detail in the forms of basic, operational, and tactical doctrine." Basic USAF doctrine, as established in AF Manual 1-1, anticipated the attack on the Republican Guard in the broadest sense. Air operations to "attack the enemy in depth" were considered an "imperative of effectively employing aerospace forces" by the authors of the 1984 version of Basic Aerospace Doctrine of the United States Air Force. More explicitly, air commanders were urged to exploit airpower's "devastating firepower" to disrupt enemy momentum and "place his surface forces at risk" with attacks on enemy forces in "reserve or rear echelons." Such attacks fell under the category of air interdiction (AI), which was intended to "delay, disrupt, divert, or destroy an enemy's military potential before it [could] be brought to bear broadly against friendly forces." Although attacks on distant ground units have always been a subset of interdiction, they are considered to be best accomplished along lines of communication when ground units are moving and vulnerable to air attack.
Official operational-level doctrine was completely unsuitable for preparing USAF units for the attack on the Republican Guards because it focused entirely on enemy lines of communication. Prescribing attacks to disrupt the flow of "personnel, supplies, and equipment . . . required to sustain the enemy's war effort," AFM 2-1, Tactical Air Operations was written in 1969 and reflected contemporary interdiction efforts being used in Southeast Asia. Elusive enemy forces were not considered to be a suitable target for interdiction. Instead, interdiction efforts were directed against lines of communication, enemy concentration points, supply stockpiles, and reconstitution facilities. AFM 2-1 described the protracted interdiction battle waged over the Ho Chi Minh Trail. After Vietnam, however, the possibility of a rapid Soviet blitzkrieg across Western Europe threatened to render this mode of interdiction less than optimal.
"Semi-official" operational doctrine developed in the early 1980s had a much more profound effect in shaping the Air Force that would counter the Republican Guards in 1991. Developed in response to political requirements for increased conventional capability against growing Warsaw Pact conventional capability, the USAF's Tactical Air Command (TAC) and the Army's Training and Doctrine Command (TRADOC) developed the joint operational concept of joint attack of the second echelon (J-SAK). Published in 1982, J-SAK was an important adjunct to the U.S. Army's airland battle doctrine. J-SAK was "semi-official" doctrine because its approving official, General W. L. Creech, (TAC commander), could not speak for the entire USAF, nor was TAC a warfighting command: its role was to provide forces for the theater commanders-in-chief. Tactical Air Command Pamphlet 50-26 (J-SAK) described a deep battle against second echelon units that was intended to provide time and space for ground commanders to win the close battle being waged with the first echelon.
J-SAK was designed against the specific threat of echeloned attack posed by Soviet tactical doctrine. Echeloned attacks would "attempt to retain the initiative by maintaining momentum and rapidly exploiting the success of . . . first echelon forces." Although 50-26 briefly noted the possibility of countering a "U.S.-type reserve" force vice a Soviet-style second echelon, virtually all other discussion focuses on defeating the Soviet model. Key elements of the Soviet doctrine included a fast-paced attack by a numerically superior enemy, continuous operations to sustain initiative and momentum, and the reinforcement of success until the enemy is defeated. Second echelon targets included "combat forces, their support elements, as well as lines of communication."
Follow on Forces Attack (FOFA) was a similar doctrine approved by NATO's Defense Planning Committee in November, 1984. Beginning in late 1979, the SHAPE (Supreme Headquarters Allied Powers Europe) staff developed FOFA to bolster the alliance's conventional capability against Soviet offensive doctrine and a "continuing massive Soviet conventional forces build-up." Closely related to J-SAK, FOFA was more authoritative and prescriptive, but geographically limited to NATO's theater of operations. FOFA was designed to attack enemy forces "from just behind the troops in contact to as far into the enemy's rear as our target acquisition and conventional weapons systems will permit."
The aim of J-SAK and FOFA (hereafter combined and referred to as "deep air attack") was to delay, disrupt, or destroy second echelon mechanized units. This operational concept optimized airpower's ability to impose an "intractable dilemma" on the enemy commander: if the second echelon attempted to advance rapidly (as Soviet doctrine prescribed), it would be vulnerable to air attack. If advancing forces took defensive precautions against the air threat (through dispersal and camouflage), they would be unable to maintain a rapid rate of movement. Maximizing the advantages of synchronized air and ground efforts, deep air attack principles resonated with many airmen.
Despite J-SAK's authoritative limitation and FOFA's geographical limitation, the combination of the two had a powerful impact on USAF equipment and tactics. Based in part on emerging weapon and sensor technologies, deep air attack generated the requirement to develop several weapons systems that would eventually be used against the Republican Guard. The most pressing need was to develop sensors capable of looking deep behind enemy lines and detecting advancing second echelon forces. Joint Surveillance Target Attack Radar System (JSTARS) was the Army/USAF solution; its powerful radar was capable of tracking moving vehicles over wide areas of the battlefield or examining selected fixed sites in a narrower mapping mode. Another capable radar, Advanced Synthetic Aperture Radar II (ASARS II), was fielded on the TR-1 aircraft, and dedicated down-link and command and control systems were deployed to take advantage of the real-time imagery available.
The USAF and U.S. Army fielded several air-to-ground delivery systems that enabled deep air attack, including the F-15E long-range interdiction aircraft, F-16C fighter-bombers equipped with radar capable of tracking moving vehicles, and night navigation and targeting systems (Low Altitude Navigation Targeting and Infrared for Night--LANTIRN). Advanced anti-armor weapons developed and deployed during the 1980s included the imaging infrared (IIR) AGM-65D Maverick Missile, an advanced cluster bomb--the CBU-87 combined effects munition (CEM), and an air scattered anti-tank and anti-personnel mine--the CBU-89 Gator. Army systems included the multiple launcher rocket system (MLRS), Army tactical missile system (ATACMS), and Apache attack helicopter.
Employment of these weapons systems is described in USAF tactical doctrine. Tactical doctrine outlines a broad range of tactical considerations in the 3- series multi-command manuals (MCM). There are separate volumes for each type of combat aircraft, a general planning volume, and an enemy threat volume. Standardized volume outlines and chapter headings result in the consideration of a wide variety of potential missions. Tactical considerations described in these volumes are not prescriptive, but are intended to "stimulate thinking." MCM manuals "consolidate tactical considerations learned from past armed conflicts, operational evaluations, training exercises, tactics development programs, and analyses of the threat." Updated on a twenty-four month cycle, MCM 3-1 is a living document reflecting tactical thoughts of the combat air forces. Each volume encourages "personal initiative and innovative thinking. . . to improve our combat capability" and challenges "all echelons of the combat air forces" to "build and expand on these tactics."
MCM 3-1 discusses the best available thoughts on a variety of potential missions. Its scope, however, is too wide to guide Air Force training and preparations; finite training resources and time limitations force tactical units to make choices and establish training priorities within 3-1's repertoire. Although headquarters staffs determine minimum semi-annual training events for combat crews, the real tactical emphasis is determined within a flying squadron by the combined efforts of the commander, operations officer, flight commanders, and weapons officer. Normally following general guidance provided by the squadron commander, flight leaders conceive hypothetical scenarios, determine tactics, and evaluate performance during routine training missions. Although Pacific-based squadrons had a Korean orientation, most other TAC and USAFE squadrons were focused on the European scenario and prepared for it throughout the 1980s. All but one of the USAF wings that participated in Operation Desert Storm had formal tasking for the European theater in the event of war.
The bulk of TAC's tactical training was geared towards executing deep air attack in the European environment. The Air Force's premier training program, Red Flag, emphasized deep interdiction in large "gorilla formations" to counter high threat environment. The exception was USAF close air support (CAS) training, for A-10 wings, which concentrated attention on high threat, low-altitude employment along the front lines to support an Army pressured by large enemy mechanized units. Many crews were exposed to flying in Europe during overseas assignments or frequent training deployments to European bases (called "Checkered Flag" deployments). TAC's only fighter wing free from European tasking, the 363d TFW, shared the remainder of TAC's tactical vision. Wing training focused on low-altitude deep attacks against a a Soviet mechanized thrust into north Iran. Virtually all air-to-ground training throughout the tactical air forces (TAF) involved low-level navigation and weapons deliveries, which were required for survival on the high-threat battlefields of central Europe, and for target acquisition which could be impaired by low European ceilings.
Despite its Eurocentric orientation, the USAF's philosophy guiding weapons acquisition and training built in considerable flexibility. Most of the USAF's air-to-ground weapons systems were designed to perform several missions in a variety of environments (high-or low-altitude attack, in day or night). The swing-role F-15E and F-16 are prime examples. They were well-equipped with highly-capable radars capable of functioning in air-to-air or air-to-ground modes, and the latest air-to-air and air-to-ground munitions, and comprised most of CENTAF's fighter force. CENTAF's B-52 bombers had proven their flexibility long before Desert Storm. Specialized fighter aircraft were present in more limited numbers. The F-111 was optimized for night low-altitude interdiction, and the A-10 was designed for day low-level CAS. Both, however, proved versatile enough to operate in unanticipated environments. The major exception was the F-117 stealth fighter: with its highly specialized role of night precision penetration and limited bomb load had limited utility in other missions. USAF munitions were another key to flexibility. Radar fuses permitted all-altitude employment of cluster bombs (CBU), while guidance kits of U.S. laser guided bombs permitted a wide range of delivery options. Flexible USAF weapons and munitions characteristics were of major significance because they allowed a considerable margin for error in tactical doctrine or practices.
Realistic and demanding training allowed USAF crews to accomplish unanticipated tasks in unexpected situations. Day-to-day training of aircrews emphasized tactical employment in realistic scenarios developed by flight leaders. Frequent multi-unit exercises and composite force training with dissimilar aircraft (such as that done at Red Flag) built familiarity with other systems and enabled crews to solve different tactical problems. Nellis AFB NV, home of the Tactical Fighter Weapons Center (TFWC), played a key role in the training of these combat aircrews. Red Flag is a recurring training exercise conducted at Nellis to expose crews to the most realistic combat environment possible; it provides an opportunity to solve difficult tactical problems in a controlled environment. Adversaries for Red Flag exercises were often provided by the Aggressor Squadrons, two specialized units that simulated Soviet tactics. The Fighter Weapon School (FWS), also located at Nellis, is a graduate-level tactics school that cultivates aggressive problem-solving in a select group of USAF crews. FWS students are required to solve a wide variety of demanding tactical problems throughout the course. Once back in their squadrons, FWS graduates (called "patch wearers" or "target arms" due to the distinctive patches awarded at graduation) provide a foundation of tactical know-how and problem solving within the unit. The thinking, teaching, and flying conducted at this center would have a powerful influence on USAF conduct in the Gulf War.
Both forces were products of their times and experiences: the Iraqi Army was a product of the static war of attrition with Iran, U.S. forces were products of the Cold War. Neither had tactical doctrines that adequately anticipated the Gulf War. USAF training, flexible weapons systems, and a core belief that "flexibility is the key to airpower" provided a sizable margin for errors in USAF doctrine.
