7th Special Forces Group Airborne 2nd Battalion Bravo Company Operational Detachment Alpha ODA-7221 Army Challenge Coin

This is a large 2 1/2 inches in diameter coin.

NOTE:  There is a OMEGA ymbol.  Not sure for the meaning whether OMEGA Kill Missions  for the CIA HVTs or they are OMEGA males:  the omega male is more introverted and isn't afraid of doing his own thing and making up his own rules in life?
