A regiment is a military unit, composed of variable numbers of battalions, commanded by a Colonel. A regiment can be broken into two distinct categories, one being an administrative unit which is responsible for non-operational management of battalions (such as human resources , training and strategic reserve), while the other being a deployable combat arm varying from a battalion to a brigade sized formation, usually with organic supply and support. Depending on the nation, military branch, mission, and organization, a modern combat regiment resembles a brigade, in that both range in size from a few hundred to 5,000 soldiers (3 to 7 standard battalions). Generally, regiments and brigades are grouped as divisions. The modern regiment's size varies in number, scope and administrative role from country to country (and might not exist in some military forces) and sometimes even within the military of the same nations.
