A battery commander, or "BC" is a Major (like his infantry company commander counterpart). However, in these armies the battery commander leads the "tactical group" and is usually located with the headquarters of the infantry or armoured unit the battery is supporting. Increasingly these direct support battery commanders are responsible for the orchestration of all forms of fire support (mortars, attack helicopters, other aircraft and naval gunfire) as well as artillery. General support battery commanders are likely to be at brigade or higher headquarters.
