Type 4 Ka-Tsu

[Grzegames]

No, the Type 3 machine gun is based on the M2 Browning machine gun, and the Type 93 machine gun is based on the Hotchkiss M1930 machine gun.
The ammunition is the same, but everything else is different. Different effective range, different spread, different rate of fire, etc.
