the recon commander is crap
Forward obsevers: adds like 2 sight range, pretty negligible and doesn't really give any real advantage.
I&R pathfinders: range on artillery is really low.
Greyhound: good AI but useless in AT.
Recon run: only useful ability
Airdroped combat group: Gives two decent units and an empty AT gun. Way overpriced and useless that late in the game.
So yeah, almost everything in it is pretty underpowered right now, which seems to be a trend with US doctrinal abilities and call-ins.
