|Notes||As early as 1940 the US ordinance board requested a need for an anti-tank gun of at least 75mm, this resulted in a combination of the 3in T9 anti-aircraft gun and the 105mm M2 howitzer carriage. Further modifications took place and the results were that the 3in was in fact a better weapon than the 75mm. The weapon itself was very heavy which didn’t please the Infantry, plus the tank destroyer department didn’t want another towed gun due to the mobility of the GMCs. The 3in was therefore cancelled. But due to pressure from General McNair the weapon got a second chance and trials began in September 1942 with 1000 guns produced by December. The M5 was first used in action in Italy in October 1943. A few of the guns that made it to Italy were mounted on the M1A1 carriage which featured a flat gun shield, but all others were mounted on the M6 carriage which had a sloped gun shield. The gun was heavy when manhandled but proved to be effective when in position. It saw action on the Italian front and in Northern Europe before being replaced by tank destroyers after the end of World War Two.|
