Administratively batteries were usually grouped in battalions, regiments or squadrons and these developed into tactical organisations. These were further grouped into regiments, simply "group" or brigades, that may be wholly composed of artillery units or combined arms in composition. To further concentrate fire of individual batteries, from World War I they were grouped into "artillery divisions" in a few armies. Coastal artillery sometimes had completely different organizational terms based on shore defence sector areas.
