Special Tactics

 Special Tactics was a division of the United States Military, subject to special training and exercises for a better performance on the field. The most notable member of the Special Tactics unit is Leland Bishop, who later became the leader of MECH, an organization intent on examining Cybertronian technology to construct their own robots and fight against the United States government.

Agent Fowler also suspected that Silas recruited members from Special Tactics, which explains why they are wearing masks to conceal their true identity.
