I thought of third one that is basically just a combination of those:
Spread out the support pieces, and have each one earn different points on top of their ability.
HQ = Aircraft points
Ammo Dump = Soldier points
Fuel Depot = Vehicle points
It adds more strategy as to what you want to hold. I’d say 2 ammo dumps, 1 HQ, and 1 fuel depot would probably make it the most fun.
