[3][4] Additional efforts were made by the Imperial Japanese Army to produce greater anti-aircraft mobilization.

This included the production of the 20 mm AA machine cannon carrier truck, using the Type 98 half-track Ko-Hi to tow an anti-aircraft gun and the creation of a prototype variant known as the Type 98 20 mm AA half-track vehicle.

Two versions of the Type 98 Ko−Hi half-track prime mover were produced.
