Or if I wanted to kill infantry, I could just get a Stummel?
It's a TD, and as a TD, yea it has 50 range, but its pen against almost all vehicles is pretty lackluster.
First half of my post was laced with near-lethal levels of sarcasm.
Hetzer functions on a similar principle to the Geschitz, it outranges all of the things it is designed to engage and is a relatively cheap piece for what it does.
Last time I checked it's FU is around 175, which is a pretty small price for the capacity to range and whittle down opposing armour that is more expensive than it. It'd do straight up damage when you needed it as well, if the camo was put to vet 0 with 2.5 second cloak time.
