Crusader Mark IIs of the British 8th Army on the move. While the Crusader was plagued with mechanical unreliability and lack of firepower and protection, it could move fast, and travel over ground that would bog down other tanks. Crews lived in their tanks; the lead vehicle has helmets, storage boxes, and packs slung around its hull. Tank crews would add railings to the outside of tanks, form a tent, and live in the desert during campaigns. Because of the mechanical issues, tanks had to be transported on trucks from the storage depots to the battlefield to prevent wear.
