The Ammunition Columns constitute also a reserve to draw on for officers, men, teams, and matériel, to replace the losses of the Batteries. In Manchuria, the men of the Ammunition Columns were, within twelve months, all absorbed by the Batteries. An Ammunition Column comprises about 150 to 200 men and as many horses, with from 20 to 30 ammunition wagons. BRITISH AMMUNITION SUPPLY In the British Service the organization of the Ammunition Supply is as follows: The Field Battery and Horse Artillery ammunition wagons carry 176 rounds per gun, those of a Howitzer Battery 88, and of a Heavy Battery 76 rounds per gun. The Ammunition Column of each Field Artillery Brigade carries 200 rounds per gun for its Brigade. It carries also rifle ammunition (100 rounds per rifle) for one Infantry Brigade. The Horse Artillery Ammunition Column carries a supply of rifle ammunition (100 rounds per rifle) for the Mounted Troops, in addition to gun ammunition at the rate of 220 rounds per gun. The Ammunition Column of a Howitzer Brigade, and that of a Heavy Battery, which have to carry heavier gun-ammunition, at the rate of 70 and 98 rounds per gun respectively, carry no rifle ammunition. The Divisional Ammunition Column is divided into 4 Sections, giving three for the three Field Artillery Brigades (carrying 120 rounds per gun), and one Section with ammunition for the Howitzer Brigade (92 rounds per gun) and for the Heavy Battery (80 rounds per gun), and also for a proportion of the guns with the Mounted Troops. Each of the first three Sections carries a reserve of 100 rounds per rifle for one Infantry Brigade. The fourth Section, having heavier gun-ammunition to carry, is not burdened with any rifle ammunition. * * * * * The number of rounds of ammunition with the Force in the field is as follows: GUN AMMUNITION Rounds.
