This is simply an attempt to cram the largest gun possible into the midget tank chassis and allow the crewman to be completely under armor. In order to allow the lone crewman to drive, fire the gun and reload it, the gun and engine are placed in the front and the crewman to the rear. It is probably best the vehicle can carry only a few shells since he will be terribly overworked. No MG is provided for local defense; the crewman must rely on a carried pistol or SMG. Tactically, the vehicle would be used as an infantry-support vehicle, moving with the infantry, which should reduce its vulnerability to enemy infantry.
The TISG has a crew of one. It uses 0.23 gallons per hour at routine usage.

Variants
American and German versions would use 75mm guns, but the stats would
otherwise be the same. Japanese versions would probably use a 70mm gun..
As an alternative that provides some anti-tank capability, the
howitzer could be replaced with a 47mm Short TG (40 rounds) or a 40mm
Medium TG (44 rounds).
