U.S. Marine Corps

In the U.S. Marine Corps, an individual's security team is called a "personal security detachment" and is assigned to the Personal Security Company.

PSD teams are often made up of private security personnel. Organizations such as Constellis, DynCorp and Triple [Canopy, Inc.] and their internal and external security departments offer armed security teams to clients traveling to war zones and areas deemed dangerous by the State Department.
