An army logistician takes a lot of guff from combat arms soldiers -- until they need their food, water, ammo and mail, and then it's all smiles and thanks. In a theatre like Afghanistan, the troops running and guarding the supply convoys are as exposed to enemy threat and action as anyone else. These British army supply vehicles of the Royal Logistics Corps (RLC) show the signs of that danger, particularly in the metal grilles and cages designed to protect them from rocket propelled grenades.
