| Notes | The Ke-Ni was another light tank and was developed to replace the Ha-Go. Up to then, all Japanese tankettes and light tanks were vulnerable to fire from heavy machine guns, namely the .50 cal Browning, so the Ke-Ni had slightly better frontal armour. It was armed with an improved 37mm type 100 gun, but unlike previous models of light tank, the turret could accommodate two crew members, the commander/gunner and loader, and this took the pressure off the commander who in the past had to fire and load the gun and command the tank. Because the Ke-Ni came late in the war and only built in small number, most of them were kept in Japan to defend the home islands against invasion, but some reports say a few saw action in Manchuria. |
