The Ordnance QF 2-pounder is a British 40mm anti-tank gun used primarily in the early stages of WW2. It was quickly realised to be obsolete against contemporary Soviet armour, but it was still capable against the tank fleets of other Eurasian Axis forces and older Soviet designs such as the BT-7. It was also the standard anti-tank gun of the Federal Army and the main gun on its Cruiser Tank.
