Hobby Master 1/72 Ground Power Series
US Willys Jeep
with 37mm  M3A1 anti-tank gun
Wanting to replace their outdated light vehicles the U.S. Military received three tenders.
Bantam Car Company was the initial winner but couldn’t meet demand so the job went to
Willys-Overland Motors. Willys was to take the best design features of the three
submitted tenders and build a standardized vehicle. Eventually in order to meet an even
greater demand the Ford Motors Company was asked to build a similar vehicle. During
World War II there was a total of 647,870 Jeeps produced by the three companies; Willys-
Overland produced 362,841 of them.

The first dedicated anti-tank gun used by the U.S. military was the 37mm M3 gun. The
gun first appeared in 1940 and became the standard anti-tank gun for the U.S. infantry
and because of its compact size made it possible for them to be towed by Jeeps. With the
advent of larger and better armored German tanks the M3 gun was found to be ineffective
for the ETO. Since the Japanese tanks were much smaller and lightly armored the gun
was effectively used in the PTO until the end of WWII.
