The 37 mm Gun M3 was the first dedicated anti-tank gun fielded by United States forces. Introduced in 1940, it became their standard with its size enabling it to be pulled by a jeep. However, the continuing improvement of German tanks quickly rendered the 37 mm ineffective, and by 1943 it was being gradually replaced in the European and Mediterranean theatres
