Formation (military) in the context of "RAF Strike Command"

The Macedonian phalanx (Greek: Μακεδονική φάλαγξ) was an infantry formation developed by Philip II from the classical Greek phalanx, of which the main innovation was the use of the sarissa, a 6-metre pike. It was famously commanded by him during the rise of Macedon and by his son Alexander the Great during his conquest of the Achaemenid Empire and his other campaigns between 336 and 325 BC.

The Macedonian phalanx model then spread throughout the Hellenistic world, where it became the standard battle formation for pitched battles. During the Second Macedonian War (200–197 BC), Roman-Seleucid War (191–188 BC) and Third Macedonian War (171–168 BC) against the Roman Republic, the Hellenistic phalanx, both the Antigonid phalanx and the Seleucid phalanx, appeared less adaptable to changing conditions on the battlefield against the more flexible Roman legions.

III Corps is a corps of the United States Army headquartered at Fort Hood, Texas. It is a major formation of the United States Army Forces Command.

Activated in World War I in France, III Corps oversaw US Army divisions as they repelled several major German offensives and led them into Germany. The corps was deactivated following the end of the war.

In military terminology, an outpost is a location where detachments of military personnel are stationed at a distance from the main armed force or formation in a region. Outposts are usually located in remote or sparsely populated areas, positioned to observe and defend against unauthorized intrusions and surprise attacks, serving as the first line of defense. The station occupied by such troops, usually a small military base or settlement in an outlying frontier, limit, political boundary or in another country. Outposts can also be called miniature military bases based on size and number of troops it houses. Oldest known use is from the 16th century "station when on duty, a fixed position or place," 1590s, from French poste "place where one is stationed,"

A division is a large military unit or formation, usually consisting of between 10,000 and 50,000 soldiers. In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps.

Historically, the division has been the default combined arms unit capable of independent operations. Smaller combined arms units, such as the American regimental combat team (RCT) during World War II, were used when conditions favored them. In recent times, modern Western militaries have begun adopting the smaller brigade combat team (similar to the RCT) as the default combined arms unit, with the division to which they belong being less important.

A group is a military unit or a military formation that is most often associated with military aviation.

Military districts (also called military regions) are formations of a state's armed forces (often of the Army) which are responsible for a certain area of territory. They are often more responsible for administrative than operational matters, and in countries with conscript forces, often handle parts of the conscription cycle.

Navies have also used a similar model, with organizations such as the United States naval districts. A number of navies in South America used naval districts at various points in time.
