Hold fire should just apply to the pintle mgs as well, it's really annoying when you reveal a unit you're trying to hide because your tank tries to shoot down the plane.
The problem is, you would need an extra ability for that, so MGs really stop shooting. A real passive modus.
But again, I really think the MG on StuG G is useless. Maybe a real silence ability can help.

Why not rename StuG G to StuG F. Same stats, same price BUT:
- remove the Vet2 skirts, instead split the Vet3 relaod a little bit.
- option to upgrade StuG F to StuG G when T4 is searched.
-> 100mp and 15fuel for skirts (Vet2 hp and armor buff) and +5 range.
Edit: that wouldn't destroy the current balancing, but would increase the performance of StuG a little bit, if you need it in late-game to counter tank-hunters it can penetrate. So it still has problems versus Churchills etc. so Panther or PaK40 will be still needed. So also an answer for the Jackson thread.
