Just noticed this. The type of chopper could be significant. Do you remember if they had two very large rotors above a "mast" front and rear? That would be a cargo bird like a CH-47. These can haul one or two HumVees or a platoon of (40 or so) troops. It is somewhat ungainly and elongated. It sort of reminds one of a grasshopper. BUT a chopper with ONE HUGE overhead rotor and a smaller rotor perpendicular off a tail boom might be a "Pave Low" and those are used by Special Operations guys. Did you notice colors or camoflage patterns? Things for everybody to watch for in the future.
Everybody should be cognizant of the different types of military helicopters which have their own specialized missions. Seeing them in numbers or at certain times can help you figure out what's happening and to whom.

In the link, the drawing is the CH-47 and the photos are the Pave Low SpecOps bird.
