The FBI Washington, D.C.’s Field Office was located in an area called Buzzard Point. The patches feature a buzzard sitting on top of an FBI Seal. The first version does not have any numbers listed on it. On the second version is the number 301, which was the call sign of a team member who was killed. Later patches also have the number 4201, signifying the only other team member to be killed.
