Background
DePuy reforms and Active Defense
The basic concept of the Blitzkrieg and similar doctrines was for the attacker to secretly concentrate his forces across a limited frontage to gain a local superiority over the defenders, culminating in an attack with at least tactical surprise leading to a breakthrough, which is then rapidly exploited to threaten the rear areas and destabilize the entire defensive position.
Conventional war
As the Vietnam War wound down, the US Army started studying their organization and structure, looking for ways to better align it with real-world conflicts. The U.S. Army Training and Doctrine Command (TRADOC), under the direction of General William E. DePuy, was formed in 1973 to study these issues and produce updated doctrine for Army forces.
TRADOC concluded that there were two main possibilities for future conflicts, a major armored conflict in Europe, or a primarily infantry fight in other locations around the world.[3] The latter possibility led to the Rapid Deployment Force, and in time, the formation of United States Central Command. The former was more problematic given the Warsaw Pact's massive numerical superiority, especially given the ending of the draft.
Rapid wars, forward defense
When the Yom Kippur War broke out in 1973, it demonstrated a new lethality of conventional weapons, especially the anti-tank guided missile (ATGM).[4] The new vulnerability of tanks, combined with the improved defensive power of the infantry, led to a revolution of thought within the US Army—that a war in Europe was winnable with conventional weapons. Impressed by the new weapons, DePuy started the process of re-arming the heavy divisions with weapons that would dramatically improve their firepower.[5]
In DePuy's view, firepower had increased so much that war would be won or lost almost immediately, in the first few massive battles.[6] As Field Manual 100-5 noted, "The US Army must above all else, prepare to win the first battle of the next war."[7]
Since forces from the rear could not move forward quickly enough to take part in the titanic battles being envisioned, everyone had to be placed as close to the front lines as possible. The result was a new battlefield organization that moved the vast majority of US and allied forces much closer to the border between East and West Germany, in what became known as "Forward Defense".[8][9][10] As reinforcements from the US could play only a minor role, the war was a "come as you are" affair.[3] Air power was key; as the battle increased in tempo and the Soviet forces attempted to break through the defenders, channels would naturally form that would be attacked by air.
A 1975 study showed that:[11]
- The main battle tank and attack helicopter are highly compatible weapons systems that are best employed using offensive principles where their mobility, firepower, and survivability can be optimized.
- The bi-dimensional mobility capabilities and overlapping firepower characteristics of the main battle tank and attack helicopter are desirable and enhance the ability to achieve a favorable exchange ratio on the battlefield.
- The main battle tank, complemented by the attack helicopter, will remain a decisive antiarmor weapons system for the foreseeable future.
One problem that was noted soon after the introduction of the 1976 version of FM 100-5 was how to deal with the enemy's reserve forces in the rear. There was the possibility that the US could win the first battle, only to meet a second unattrited reserve force soon after. A solution to this problem was not immediately forthcoming.
The results of war gaming the Active Defense doctrine was that by using this doctrine "you would lose every time."[12]
Military historian Gwynne Dyer also criticized the defence strategy as militarily senseless, used only because an effective defense in depth doctrine was considered politically unacceptable to West Germany since that would mean much of the country would have been overrun by Warsaw Pact forces in an invasion before they could be stopped. As a result of the political compromise, a concerted Warsaw Pact invasion would likely have been able to break through the thin defensive zone with their numerically superior conventional forces easily, which would have soon forced NATO to resort to tactical nuclear weapons to counter it, which would have likely escalated the war to a full-scale global nuclear war. Furthermore, the doctrine was considered by the Warsaw Pact to be a threatening policy, which they feared would have meant an inverted in-depth defence by NATO in an aggressive fashion which could have entailed invading the Warsaw Pact as a pre-emptive move to create the defensive buffer zone in Soviet territory necessary to prevent a Soviet incursion, thus increasing the possibility that Warsaw Pact forces could have decided to make the first aggressive move themselves to forgo that attack, thus increasing the risk of war.[13]
Patterns of Conflict

Main article: Patterns of Conflict |
In 1976 Colonel John Boyd presented Patterns of Conflict, a study outlining a number of historical matchups in which the victor was able to disrupt the "observation-orientation-decision-action time cycle or loop" of their enemy. This, he stated, made them "appear ambiguous (unpredictable) thereby generate confusion and disorder". His primary example of such action was the Blitzkrieg, where highly mobile forces were quickly concentrated at small points and then used to force a number of simultaneous thrusts through the front.[14] Blitzkrieg aimed at forcing the enemy into a continuous battle of maneuver instead of an outright fight, bypassing any strongly defended areas and extending into their rear. To guarantee supply movement and avoid being encircled, the enemy is forced to retreat in an attempt to reform continuous defensive lines.
The traditional method of dealing with an armored breakthrough was to pick away at its sides, forcing it to maneuver away to find less-defended areas of advance. If these spoiling attacks can be set up on both sides of the route of attack, the armored spearhead is forced into an ever-decreasing frontage, eventually being pinched off and losing the ability to maneuver. The classic example of a successful anti-Blitzkrieg was during the Battle of the Bulge, where US units repeatedly forced the German spearhead inward, eventually pinching it off just short of the Meuse River. However, this approach required the forces to be deployed in depth, and the massive numerical superiority of the Warsaw Pact was the reverse of the numbers during the Bulge. Additionally, the concentration of low-mobility forces that formed the channelizing groups would invite nuclear strikes.
Instead of meeting the Blitzkrieg head-on, Boyd suggested what he called the "counter-blitz", where small groups of equally mobile forces would pick away at the lines of thrust and then move on to the next in a series of hit-and-run attacks. There was no necessity to retain any sort of front line, and the attacks deliberately moved from point to point to avoid being bogged down or getting trapped. The idea was not to force the blitz to lose its ability to maneuver, but instead upset its ability to understand where it should be maneuvering to—the attacker would have no idea which of these counteroffensives represented a real threat, and would have to respond to all of them. The key idea was to "Smash blitz offensive by inconspicuously using fast-tempo/fluidity-of-action and cohesion of counter-blitz combat teams as basis for shifting of forces and quick focus of air and ground effort to throttle momentum, shatter cohesion, and envelop blitz in order to destroy adversary's capacity to resist."[15] The battle was less about the weapons than it was about the ability to command them; it was believed that the U.S.' devolved command structure would be able to react to changes on the battlefield more quickly than their Soviet counterparts, overwhelming the Soviets ability to maintain cohesion as their higher-echelon commanders became overwhelmed with reports from so many small actions.
Whereas Active Defense envisioned the Army units moving from one blocking position to another in a series of largely static defenses, in the counter-blitz they would be far more mobile, conducting a series of limited offensives instead. Another difference was the role of the reserves; under Active Defense their role was very limited and even battlefield reserves were expected to be placed directly in the front, but under Patterns the reserves could be introduced where and when they became available, and be just as effective as the troops that had been there from the start. Boyd felt that the continual pattern of harassment and shifting positions could continue throughout a conflict, as opposed to attempting to win the entire war at the front in a single battle.
When Boyd introduced the concept, the Pentagon was being led by power groups that new inductees considered hidebound and moribund. As illustrated in The Pentagon Wars, Boyd and like-minded up-and-comers formed the "Reform Movement" and sought to overturn existing chains of command and introduce new weapons and tactics across the entire armed forces.[16]
Extended battlefield
The major driving force in the evolution of AirLand Battle was General Donn A. Starry, who had taken over TRADOC from DePuy in 1977 and had been the primary force in implementing Active Defense. Since its introduction Starry had been attempting to find solutions to the problems of the enemy's reserves, and had been developing the concept of the "extended battlefield".[17] This was a far more aggressive strategy, and required of the Army to fly its own CAS attack aircraft like the A-10 and the AH-64, as well as to better integrate USAF high-boy capabilities. It also gave birth to HIMARS, Bradley IFV, M109 Paladin, Patriot missile, M1 Abrams,[12] and the Lockheed F-117 Nighthawk.[18] President Carter approved the novel weapons programs.[12]
The extended battlefield noted that different commanders had different views of the battlefield in geographical terms. The brigade commander had to consider actions beyond the immediate front lines, up to 15 km into the enemy's rear where his artillery was operating. The division commander considered the battlefield as far as 70 km out, while the corps commander had a field of view out to 150 km. Starry introduced the idea that there was not only a geographical dimension to the battlefield organization, but a time dimension as well; the brigade had perhaps 12 hours to respond to actions, while the division had 24 and the corps 72. It was this coordination both in space and time that defined the extended battlefield.
The reason that the time dimension was important was the result of studies in nuclear weapon employment at Fort Sill, Oklahoma, in December 1979. These studies demonstrated that interdiction in the enemy's rear could seriously delay the movements of the rear echelon forces and create "time windows" during which the US would have the tactical advantage.[19] By ensuring that the command structure was aware of the time dimension of the battlefield, they would be better prepared to take advantage of these windows when they occurred.
FM 100-5 draft
When Active Defense had been introduced in 1976 it faced a wave of criticism, both from within the Army, and from highly influential civilian advisers outside. Having witnessed this first-hand, Starry took measures to ensure this would not happen a second time. Foremost in these efforts was the early dissemination of the concept through briefings and wide circulation of Fort Leavenworth's draft of the new FM 100–5 in 1981.[20] These were well received, especially its newly offensive orientation, which it summed up neatly with this statement:
... once political authorities commit military forces in pursuit of political aims, military forces must win something—else there will be no basis from which political authorities can bargain to win politically. Therefore, the purpose of military operations can not be simply to avert defeat—but rather it must be to win.[21]
AirLand Battle became the primary battleplan of US forces in 1982,[22][23] and NATO forces in 1984,[24][22][25] with the help of SACEUR General Bernard W. Rogers.[26] Its roll-out required upgrades to the C3I equipment of all branches of the military, along with similar changes in the command and control structures to take advantage of the massive amounts of information the new C3I assets would be generating.
