I mean, for those feared of the Stock grind to get back the MG, it could also be the other way around, to research the removal of the MG. Combined with a Crew actually looking out of the tank.
Example the “Zerstörer 45” Which can research moving the wall up, but stock they are down.
I would love that. It would be a nightmare to implement tho.
The M18 allready has it.
But I would assume most non-opentop tanks would need a serious amount of remodelling for this feature
Most of them do anyway, most models are outdated anyway.
Some vehicles from what I understand would need to have part of the roof open to accommodate the machine gun. More work then.
