well min range is actually a thing that every tank should have not sure why only ostwind has it. kinda silly seing the tank gun barrels inside the enemys tank and then shoot lol
Yeah, a min range of 3... probably to simulate that it is an AA gun and can't aim down, a bit like the flak in CoH1. Though tanks can't shoot at such short ranges either without damaging their gun and optics... so no idea why they don't have it. Probably so circle strafing etc. doesn't get even messier.
Probably simulates firing 37mm high explosive from that close of a range while using an open top vehicle might shower the crew with their own fragments ;o
