Maritime Special Purpose Force
The United States Marine Corps' Maritime Special Purpose Force, or MSPF, are a unique specialized sub-unit that are drawn from the Marine Expeditionary Units' (MEU) major subordinate elements. They are special operations capable forces deployed to give the commanders low profile, two-platoon surgical emplacement in the accessible littoral regions. The MSPF provides the enhanced operational capability and precision skills to complement, enable, and execute selected conventional, maritime special operations. They can also perform operations not resident in traditional amphibious raid companies.
The MSPF cannot operate independently of its parent MEU, on which it relies for logistics, intelligence, communications, transportation, and fire support. However, they are capable of conducting operations with, or in support of the operators of the United States special operations forces. The MSPF's task organization are often conformed as an addition of the Amphibious Ready Group’s Naval Special Warfare Task Unit detachment.
The Maritime Special Purpose Force contains a command element, security element, assault element, and support element. The security element consists of one or more reinforced rifle platoons. The assault element is organized to conduct on-scene command, assault, security, and support functions. The support element is organized to conduct reconnaissance and surveillance, sniper control and support, counter-intelligence, human intelligence (HUMINT), signals intelligence/electronic warfare (SIGINT/EW), and close air support.
The commander of the MSPF are designated by the MEU(SOC) commander. The command and control remains with the MEU(SOC) Commander.

The security element is normally structured around a platoon provided by the Battalion Landing Team (BLT) and may be augmented by the Naval Special Warfare Task Units (NSWTU) embarked within the Amphibious Ready Group. The security element will act as a reinforcing unit, a support unit, a diversionary unit, or an extraction unit.
