The 3-inch gun M5 was an anti-tank gun developed in the United States during World War II. The gun combined a 3-inch (76.2 mm) barrel of the anti-aircraft gun T9 and elements of the 105 mm howitzer M2. The M5 was issued exclusively to the US Army tank destroyer battalions starting in 1943. It saw combat in the Italian Campaign and on the Western Front in Northwest Europe.
