Churchill NA 75 infantry tank. The NA 75 was created by British Captain Percy H. Morrell in 1944. Morrell took a standard Churchill Mk IV infantry tank and equipped it with an American 75 mm M3 cannon in a slightly modified turret. The goal behind this conversion was to enable the Churchill tank to fire capable HE rounds (which its original QF 2-pounder and QF 6-pounder armaments could not do), as well as equip the tank with more turret armor. When converted, the NA 75 could effectively take out fortified targets in support of friendly infantry, which the Churchill was mostly designed to do (hence the designation of "infantry tank"). A total of 200 Churchill NA 75s were converted, equipped with the 75 mm gun, a new armored gun mantlet, and a gun counterweight in the rear of the turret. The tanks were first deployed in Italy with great success, working hand in hand with M4 Sherman medium tanks. They would remain in that particular campaign until the end of the war. |
