Regimental combat teamA regimental combat team (RCT) is a provisional major infantry unit which has seen use by branches of the United States Armed Forces. It is formed by augmenting a regular infantry regiment with smaller combat, combat support and combat service support units. The United States Army first adopted the RCT concept just prior to World War II, where it served as the infantry-centric counterpart to the Combat Command used by armored forces. RCTs were widely used during World War II and the Korean War but were disbanded after the adoption of the Pentomic structure in 1957.
Interservice rivalryInterservice rivalry is rivalry between different branches of a country's armed forces. This may include competition between land, marine, naval, coastal, air, or space forces. Interservice rivalry can occur over such topics as the appropriation of the military budget, prestige, or the possession of certain types of equipment or units. The latter case can arise, for example, when a navy operates naval aviation units, which can be viewed by the air force as an infringement of its traditional responsibilities.
Army groupAn army group is a military organization consisting of several field armies, which is self-sufficient for indefinite periods. It is usually responsible for a particular geographic area. An army group is the largest field organization handled by a single commander – usually a full general or field marshal – and it generally includes between 400,000 and 1,000,000 soldiers. In the Polish Armed Forces and former Soviet Red Army an army group was known as a Front. The equivalent of an army group in the Imperial Japanese Army was a "general army" (Sō-gun).
Military reserve forceA military reserve force is a military organization whose members (reservists) have military and civilian occupations. They are not normally kept under arms, and their main role is to be available when their military requires additional manpower. Reserve forces are generally considered part of a permanent standing body of armed forces, and allow a nation to reduce its peacetime military expenditures and maintain a force prepared for war.
Divisional generalDivisional general is a general officer rank who commands an army division. The rank originates from the French (Revolutionary) System, and is used by a number of countries. The rank is above a brigade general, and normally below an army corps general. The rank is mostly used in countries where it is used as a modern alternative to a previous older rank of major-general or lieutenant-general. The Brazilian rank general-de-divisão translates literally as "general of division", and is used by the army.
Military operationA military operation is the coordinated military actions of a state, or a non-state actor, in response to a developing situation. These actions are designed as a military plan to resolve the situation in the state or actor's favor. Operations may be of a combat or non-combat nature and may be referred to by a code name for the purpose of national security. Military operations are often known for their more generally accepted common usage names than their actual operational objectives.
Group (military unit)A group is a military unit or a military formation that is most often associated with military aviation. The terms group and wing differ significantly from one country to another, as well as between different branches of a national defence force. Air groups vary considerably in size and status, but generally take two forms: A unit of two to four squadrons, commanded by a lieutenant colonel, colonel, commander, naval captain or an equivalent rank.
Military districtMilitary 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.
MilitaryA military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats.
Military aviationMilitary aviation comprises military aircraft and other flying machines for the purposes of conducting or enabling aerial warfare, including national airlift (air cargo) capacity to provide logistical supply to forces stationed in a war theater or along a front. Airpower includes the national means of conducting such warfare, including the intersection of transport and warcraft. Military aircraft include bombers, fighters, transports, trainer aircraft, and reconnaissance aircraft.
