Quite possibly Recon should be trimmed back or ignored completly they are doing just that. If they get caught in a fight quite likely to be seperate from the main force.
I may well be wrong here as a civillian but true recon is a seperate thing I think of the scouts we use in game as a squad trained to split & cover more ground.
More scouting for contact than true Recon who probably gave you the local & are now trying to figure out force makeup etc.
So thinking is might have left a few behind to keep an eye on but the rest have moved on.
