I would hope that the changes made to vis ranges for vehicles apply to both sides evenly. That is to say, I shouldn't be able to pick out friendly GV's from thousands of yards away when enemy GV's can only be con'd from hundreds of yards away.
If folks need to know where the flak cover is to run to, use a radio. Feints of realism obviously being the intent here, that's how it would have been done in a real enviorment. A GV camo'd in tree's is just as hard to see for friend or foe.
That part is really important imo.
Also (and I have no idea how this works currently) if there are new vis limiters from the air based on movement or cover, those thould apply on the ground as well. Again, assuming they don't already.
