The Type 94 was the standard infantry antitank gun of the Japanese Army during World Ware Two. It was developed in the early 1930s as tensions with the Soviet Union rose; there had not been much need for Japanese antitank weapons in China. However, high explosive ammunition was also made for the gun, and it was used in an infantry support role with HE in China as well as in the Pacific.

The Type 94 was small and light, and could be disassembled for transportation without vehicles - a very useful capability on islands like Guadalcanal. Against US M3 Stuart light tanks, the Type 94 was a reasonably potent weapon.

Note that the Japanese also had a Type 94 tank gun, which was not the same as this - and did not use the same 37mm cartridge.

This trip to Guadalcanal was made possible by War Historian Battlefield Expeditions - big thanks to them!
