The organisation is for a Battery equipped with M10 3 inch Guns. Batteries with M10 17 pdrs were the same except for the following differences:
The Troop Universal Carriers (RA, RB & RC) were replaced with an OP Tank.
The guns carried 50 rounds of ammunition instead of 54. Therefore extra ammunition was needed in the ammunition vehicles.
The two 3 ton Lorries in each Troop (A5,A6 etc.) carried 80 rounds each.
