They consist of two or more platoons, usually of the same type, a headquarters, and, in some cases, a limited self-support capability.
Companies are the basic elements of all battalions.
All close combat companies can fight massed or by separate platoons. In infantry, armor, and attack helicopter battalions, companies normally fight as integral units. Attack helicopter companies more frequently fight with their platoons in separate zones, sectors, or areas. They may also be reinforced with maneuver platoons of the same or different types and with engineer squads or platoons to form company teams. The formation of company teams allows tailoring forces for a particular mission.
