A battalion unit is generally considered the smallest unit able to conduct independent operations.
Using the US Army and Marine Corps model as an example, a battalion is normally composed of three rifle/infantry companies, each designated by a letter (A through M, depending on which battalions within a single regiment a company is part of), as well as a Headquarters and Service Company (H&S Company) (Marine Corps) or a Headquarters and Headquarters Company (HHC) (Army) including the commanding officer (usually a Lieutenant Colonel or Colonel) and executive officer (usually a Major), a Sergeant Major and executive staff. These are usually supplemented by a Weapons Company, which does not use a letter-designation.
A Regiment or Brigade is composed of several battalions.
