The US Army developed the 37mm anti-tank gun in response to needs identified during the Spanish Civil War. By the time it entered service in Tunisia in 1943, the gun was already obsolete.This compact guide explores the US' manufacture of anti-tank artillery over the changing course of the Second World War. They next began developing licensed manufacture of the British 6-pdr in the hope of finding a quick solution to its artillery requirements. This in turn proved unequal to the demands of warfare in France in 1944, and further anti-tank measures were developed – rocket propelled grenades for infantry use, and weapons designed specifically for use by the Tank Destroyer Force.Steven J Zaloga charts the artillery development from 1941 to the end of the war, his text accompanied by specially-commissioned artwork.
