Nigel,
The Royal Army Ordnance Corps was the storekeeper and supplier to the Army. They would supply and repair uniforms, inc boots, repair tentage, etc., vehicle and parts, tyres, furniture, food and rations, you name it they supplied it. It might seem the the word "ordnance" refers to weapons and ammo, but that is only part of their role...or was, now joined together with RCT, successors to RASC, to form RLC
