| Notes | The Ha-Go was the most numerous Japanese tank of the period. It was planned to be used in the infantry support role and to keep pace with infantry attacks and breakthroughs. It had a three man crew and was armed with a 37mm Type 98 gun and a couple of 7.7mm Type 97 machine guns. It first saw action against the Chinese and was successful against light opposition, which had no real anti-tank defense. In 1939 they were used against the Soviets in Manchuria and caught the Russian by surprise by utilizing their speed to get close to the Soviet positions. They took part in the conquest on Malaya, Burma and the Philippines. By 1944 the Ha-Go was hopelessly outclassed by US M3 and M4 medium tanks, but were still used in large numbers until 1945. |
