Yeah those are nice, but we're talking about a full-on all-out war map with AI tanks and such, maybe with battalions of Rhinos and Grizzlies clashing head on, perhaps in groups (2 Rhinos+ 1 Flak Track, 3 Grizzlies) similar to what the AI would periodically send after you. Then the players could support these groups or take an alternate route to the enemy base and make a surgical strike. Of course, similar packs (8 Conscripts, 3 Tesla Troopers, 8 GIs, 4 GGIs) would be made for infantry, again mirroring the harassment squads sent after the player from time to time.
And, of course, this should extend beyond AR.
