| Notes | The Ho-Ro was an assault howitzer similar to the ones developed by Germany. The Germans had made good use of mounting 15cm infantry guns on tank chassis to produce a close support vehicle. The chassis used was again from the Chi-Ha medium tank and this mounted a 150mm howitzer. It suffered like the early versions of the Ho-Ni did, with the lack of protection given to the crew. It was produced in small numbers and these saw action in the Philippines and Okinawa. |
