Don't know if you care or not, but when I flew out of Logan last night I noticed many personnel from the MA State Police carrying some interesting hardware.  I'm not sure what unit they were, but they were in all black BDU's with arm patches I've never seen before.  Anyway, there was a woman on my flight who appared to be the fiance of one of the team members, so this guy and his whole team were hanging out by my gate.  In all there were six guys and their armament is as follows; one MP5SD, two M16A1's, two M16A1's with M4A3 uppers, and one real factory M4A3.  All of the M4's had C-More sights except one, which had a carry handle.  The MP5 had a mag clamp.  The exposed rounds from the clamped on mag appeared to be Winchester Ranger.  I just kind of sat there for a little over an hour drooling, and damning the NFA.  BTW, the girl they were talking to was pretty cute.

Did they have any ammo for their machine guns?
