Well, why not to make it "Gustav"? You know, sometimes it says that "Schwerer Gustav is ready to fire", when ability becomes ready to use, so... who knows.
Anyway, I think V1-like offmap stirke would be way more useful for breaking defensive lines, than those pathetic and inaccurate 3 shots. Specially for that count of ammo, which you need to spend on it.
dont reply to him, allied fanboy has spoken. ITS FINE SO LEAVE IT AS IT IS.

i like the idea overall, the gustav is only found in unused commanders anyways. it would definitly boost them. but it wont happen due to lelic being lazy, so yeah
