How about a couple of dug in positions near the airfields and vehicle bases?
I figured like a N, NE, E, SE, S, SW, W and NW fighting positons, Just a tad wider than the tank and just deep enough to conceal the body, leaving the turret exposed.
Same thing on the airbases, except off center to the runways. I would also put some near the hangars and staging area.
This would give the defenders an advantage of being in prepared fighting postions, and make it a tad more difficult for the attackers.
