[It] was the first dedicated anti-tank gun fielded by United States forces in numbers. Introduced in 1940, it became the standard anti-tank gun of the U.S. infantry 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 theaters by the more powerful British-developed 57mm Gun M1. In the Pacific, where the Japanese tank threat was less significant, the M3 remained in service until the end of the war.
The 3.7cm Pak 36 includes over 50 LEGO pieces. It's available to purchase for $15.00.
[It] was a German anti-tank gun that fired a 3.7 cm calibre shell. It was the main anti-tank weapon ofWehrmacht infantry units until mid-1941. It was followed in this role by the 5cm Pak 38 gun.
