Maritime Safety and Security Teams (MSSTs) are counter-terrorism (Force-Presence) units created under the Maritime Transportation Security Act of 2002 (MTSA) in response to the terrorist attacks of September 11, 2001. The eleven MSSTs provide both waterborne and shore-side counter-terrorism and force protection for strategic shipping, high interest vessels, and critical infrastructure. MSSTs are a quick response force capable of rapid worldwide deployment via air, ground or sea transportation in response to changing threat conditions and evolving Maritime Homeland Security (MHS) mission requirements. Multi-mission capability facilitates augmentation for other selected Coast Guard missions. Other federal agencies that MSSTs train with are the Navy's Special Boat Teams, FBI, and local SWAT Teams.
