That would be very overpowered. That along with the p47 combo would insane.
I dunno about that P-47. When I use it, it underperforms. When used against me, it's deadly . Strange feeling.
Note that I didn't say "destroyed engine" I said "damaged engine", so the german tank can still move even if it moves much slower. For an unsuported heavy german tank, that could be the end. Otherwise, I really, really doubt. If this shot would be expensive as amo cost, how manny time do you think you will be able to use the P-47 - this shot combo? Most probably (IF you use paratrooper doctrine) once per game, because, USF needs bars, zooks, fighting positions, mines, maybe some arty strikes from major, grenades throwing and so on. All these cost amo, and without them, what are the chances against Axis infantry (especially OKW)?
