Type 4 Ho-ro Self-propelled Gun

Inspired by German self-propelled guns, the Type 4 Ho-Ro assault gun was based on a reinforced Type 97 Chi-Ha tank chassis. The Type 4 Ho-Ro mounted the Type 38 150mm howitzer. The front of the howitzer was protected by 25mm of armour, though the open rear left the crew vulnerable to close combat and shrapnel.
