The 9th Division's Cavalry Regiment's Crusader Tank.
Meet the Crusader. This is the best that the British had to counter the German's Panzers. Whilst faster than the Panzer, the Crusader was lacking in every other department. It had less armour, a much smaller two pounder gun and was plagued by mechanical problems.
It also had the severe tactical disadvantage of not having a High Explosive shell for it's main gun. Whilst these shells existed they were not made available in time. Realising the severe disadvantage that they faced with their lack of armour these tanks were replaced later in 1942 by the American built Shermans and Grants which were much more capable of taking on the Panzer's of the Afrika Korps on a much more even footing. The Crusader finished the War in a support role and was more often used as an artillery tractor.
