Make tanks require a commander to operate

[Rudd]

I'd LOVE RWS systems etc on tanks for teh driver and removal of the 50cal position

but a separate commander just isn't doable with the player limit.

This theme was discussed thousand times. And every time people coming to conclusion that this is great idea. That tank needs to be controlled in ARMA2 style. But in one of these threads Rhino exposes general reasons, why this feature never will be implemented. Search for "tank commander" phrase and You'll see.
