An Ammunition Column consists of dedicated military vehicles carrying artillery and small arms ammunition for the combatant unit to which the column belongs, most noted as being the Artillery Brigade or a Divisional Artillery. Thus the Ammunition Columns of a division, formed of the brigades of field artillery, carry reserve ammunition for the guns, the machine guns of the infantry and the rifles of all arms. Generally speaking, the Brigade Ammunition Column of the Artillery Brigades furnishes ammunition for its own batteries and for one of the brigades of infantry, and each is supported by a Divisional Artillery.
