Order of battle

In modern use, the order of battle of an military doctrine of its armed force. As combat operations develop during a campaign, orders of battle may be revised and altered in response to the military needs and challenges. Also the known details of an order of battle may change during the course of executing the commanders' after action reports and/or other accounting methods (e.g. despatches) as combat assessment is conducted.

Historical approaches

In its original form during the Medieval period of European warfare, an order of battle was the order in which troops were positioned relative to the position of the army commander. The term was also applied to the disposition of ships in the line of battle during the age of sail. In the later transformation of its meaning during the European period of Early Modern warfare the order of battle came to mean the order in which the units manoeuvered or deployed onto the battlefield to form battle-lines, with the positioning on the right considered the place of greatest honour. This need to reflect the unit seniority led to the keeping of military staff records, in tabular form reflecting the compilation of units an army, their commanders, equipment, and locations on the battlefield.

During the military intelligence to analyse enemy capability for combat.

British historical approach

British military history is the source of some of the earliest orders of battle in the English language, and due to the British Empire's involvement in global conflicts over several centuries the records of historical orders of battle provide an excellent source of study and understanding not only of the composition, but also of tactics and doctrines of the forces through their depiction in the orders of battle. The British Army and UK forces use the acronym ORBAT to describe the structure of both friendly and enemy forces.

Operation Quicksilver, part of the British deception plan for the Invasion of Normandy in World War II, fed German intelligence a combination of true and false information about troop deployments in Britain, causing the Germans to deduce an order of battle which suggested an invasion at the Pas-de-Calais instead of Normandy.

Clausewitz

Clausewitz defined the ‘order of battle’ as “that division and formation of the different arms into separate parts, or sections, of the whole Army, and that form of general position or disposition of those parts which is to be the norm throughout the whole campaign or war.”

  • Division comes from the permanent peace organization of the Army, with certain parts such as battalions, squadrons, and batteries being formed into units of higher order up to the highest of all, the whole Army.
  • Disposition comes from the tactics and how these troops are to be drawn up for the battle.

Normally these tactics are exercised in peace and cannot be essentially modified when war breaks out. Order of battle belongs more to tactics than strategy. Clausewitz also noted that the order of battle depends on the effective span of control by a commander. Too few subunits makes an army unwieldy; too many subunits makes the ‘power of the superior will’ weak; and in addition every step by which an order has to pass weakens its effect by loss of force and Longer time of transmission. Clausewitz recommended that armies have no more than eight to ten subunits and subordinate corps four to six subunits.[1]

United States Army

In United States Army standing operating procedures, an order of battle to be used for operations planning should relate what an Army unit might be expected to encounter while deployed in the field. The templating of the OoB during maneuvers is typically the responsibility of a battalion or brigade commander, conducted through their Headquarters S-2 (intelligence) sections. Observations about enemy troop movements may be gathered by various military intelligence resources from all echelons, including the employment of any attached special forces units (such as Rangers or LRS teams) as well as Cavalry RSTA squadrons.

From such intelligence data, the OOB section staff compiles a likely order of battle for a planning document or operations order by assessing the following factors:

Enemy's Composition, Disposition, Strength (often mnemonicized with SALUTE: Size, Activity, Location, Unit, Time, Equipment):

  • Composition: the command structure and organisation of headquarters and subunits
  • Disposition: geographical locations of unit headquarters and subunits
  • Strength expressed in units and weight of fire delivered by its weapon systems

Enemy capabilities and limitations (often mnemonicized with DRAWD: Defend, Reinforce, Attack, Withdraw, Delay):

Enemy's Most Likely Course of Action (EMLCOA):

  • Tactics used by the enemy unit
  • Miscellaneous data related to specific task, mission or operations
  • Personalities (known enemy personnel and their behaviour, often based on communications intelligence analysis)
  • Unit history used to judge expected performance based on its past performance
  • Uniforms and insignia to enable confirmation of the above data

A general rule in American military doctrine is that each unit should keep track of enemy subunits two echelons below its own: that is, a George S. Patton was one of the first to recommend this practice.

The United States military's intelligence capabilities in the 21st century have allowed for monitoring even further than two echelons down the chain of command. It is quite common for US forces at the battalion level to be able to identify the location and activities of not only enemy forces at the squad level but even individual vehicles. This situational awareness provides a more complete picture of the battlespace for both combatant commanders and tactical commanders.

Up until the end of the Cold War, determining realistic orders of battle was generally an orderly but extremely frustrating process for NATO because although the Warsaw Pact nations had well known doctrines, tactics, techniques and procedures, in actuality, the characteristics of Soviet forces fluctuated often, significantly, and changes often went undetected for years at below-division levels. The intelligence situation for Western militaries has been exacerbated today as they continue to be become engaged in operations against non-traditional enemies (insurgents, guerrillas, etc.) and compiling orders of battle for irregular forces becomes very difficult; the equivalent military intelligence output requiring an increase in acquired data and analysis effort to provide an accurate and timely picture to the commander.

Examples

Some examples of ORBATs in modern warfare can be found for the Invasion of Normandy, the Battle of Bình Giã during the Vietnam War, and the Battle of Al Faw during Operation Iraqi Freedom.
