U. S. Coast Guard Port Security Units are Deployable Specialized Forces organized for sustained expeditionary security and anti terrorism. They provide Anti Terrorism Force Protection (ATFP) missions, which include harbor and port defense, protection of High Value Assets (HVAs), expeditionary security, Sea Lines of Communications (SLOCs), special missions. and coastal surveillance. PSUs are expeditionary units that conduct OCONUS (Outside of Continental United States) missions in support of a requesting regional combatant commander. PSUs usually operate under the direction of the Coast Guard's Pacific Area (PACAREA) command but are unique in that they are the only Coast Guard units that can be quickly requested by the Department of Defense. PSUs often operate and integrate with Marines and Navy Expeditionary Combat Command (NECC) elements. PSUs are also the only Coast Guard element that provide ground combat security capabilities to the Coast Guard. PSUs were originally part of the Coast Guard's Deployable Operations Group (DOG) until it was decommissioned; PSUs are now a part of the reorganized Deployable Specialized Forces (DSF), which includes Maritime Security Response Teams (MSRTs), Maritime Safety & Security Teams (MSSTs), and Tactical Law Enforcement Teams (TACLETS).

The Port Security program of the Coast Guard began as a result of the Black Tom explosion and the passage of the Espionage Act of 1917. The Coast Guard's Captain of the Ports (COTPs) were given responsibility for the security of port areas under this act. During World War I, port security operations were conducted by active duty personnel. After the war, interest in port security waned until pictures of burning ships visible from U. S. shores, as the country entered World War II, rekindled media and public attention. During the early 1980s, Department of Defense planners formally identified the need for port security forces in OCONUS (Outside of Continental United States) seaports. Dialogue began between the Army, Navy, and Coast Guard, and the concept of the deployable Port Security Unit (PSU) was born. In January 1985, the Commandant of the Coast Guard approved three national PSUs to respond to the requirements of Department of Defense operations plans. The three units were located in Coast Guard District 9 at Buffalo, New York; Cleveland, Ohio; and Milwaukee, Wisconsin. In addition to more recent operations around the world, PSUs were first deployed to the Persian Gulf during Operation Desert Storm in 1990. In December 2000, PSU 309 from Port Clinton, Ohio was deployed to the Middle East to provide vital force protection for U. S. Navy assets following the attack on the USS Cole. In 2003, PSUs 311 and 313 would serve in support of Operation Iraqi Freedom. In March 2003 an amphibious force composed largely of British Royal Marines, Navy SEALs and Navy SWCC had initiated an amphibious assault against Iraqi defenses on the Al Faw Peninsula, the location of many Iraqi oil facilities. The units would participate in the Battle of Al Faw (2003), an hour after the assaults on the oil terminals which had been cleared of Iraqi troops, explosives, and weapons, by SEAL and Special Boat Teams. PSUs 311 and 313 arrived to take control of the facilities. PSU boats met the U. S. Army’s large landing craft Mechanicsville and formed up in close formation near it to complete their transit to the oil facilities. PSU's helped secure and established the beachhead for USAV Mechanicsville's beach landing. A ground side element of the PSU units, reached the boat landing by convoy to help secure the port. They helped unload army vehicles and prepared for operations. While most of the coalition forces had secured the port earlier, snipers occasionally harassed the landing element and PSU's. Days later an element of PSU volunteered to move into Umm Qasr with coalition forces. NCWG One, Special boat teams
re assigned with PSU 311 from its original mission and were tasked to provide port and perimeter security at Umm Qasr on the Khor Abd Allah Waterway during the Battle of Umm Qasr. Meanwhile, remaining members of both PSU 311 and PSU 313 back filled port security needs at the back at the port of Ash Shuaybah.

After completing individual A school training for their respective jobs, members of Port Security units receive their training at the Marine Corps Base Camp Lejeune's Special Missions Training Center. Various skills are learned and trained which include close quarters combat, CBRN defense, tactical combat casualty care (TCCC), land navigation, entry control points (ECP), vehicle searches, rear area security, crew served weapons like the M240B and M2HB, military operations in urban terrain (MOUT), convoy operations, patrolling, individual and squad movement. A series of practical exercises, live fire training, and a final combat problem are also conducted.

PSUs are the Coast Guard's expeditionary forces and are a quick response force capable of rapid worldwide deployment They can deploy within 96 hours and establish operations within 24 hours of arrival. The main purpose of the Waterside Security Division is to provide maritime protection to key High Value Assets (HVAs), such as warships and military supply vessels, military bases, ports, harbors, and piers. Through the use of vigilant escort and patrol techniques, the HVA is protected from asymmetrical threats, such as assaults by small boats or swimmers. The Waterside Security Division consists of Boatswain's Mates (BMs), Gunner's Mates (GMs), Machinery Technicians (MKs), and Maritime Law Enforcement Specialists (MEs), led by a division officer (DIVO) and assistant division officer (ADIVO). Each Transportable Security Boat (TPSB) is crewed by enlisted personnel, consisting of a Tactical Coxswain and Tactical Boat Crew members, one of which is a qualified Engineer. Members of the Waterside Security Division as well as the Shoreside Security Division and Weapons Division use a variety of light and crew served weapons, including 7.62mm M240B Machine Guns, .50 caliber M2 Machine Guns, M4 Carbines, .40 S&W SIG Sauer P229R DAK Service Pistols, 40mm M203 grenade launchers, and 12 Gauge Remington 870 Shotguns.

The Shoreside Security Division (SSD) is the ground element of the PSUs. They are often tasked with providing protection to vessels in security zones and pier areas and security for internal unit functions, such as joint command areas, communications centers, berthing areas, entry control points (ECP), and vehicle control points (VCP). SSD personnel are also trained in defensive position construction, convoy operations, individual movements, and patrolling. The Shoreside Security Division consists of Maritime Law Enforcement Specialists (MEs), led by a division officer (DIVO) and assistant division officer (ADIVO). It is subdivided into squads with 3 four person fireteams each. Each squad and fireteam has a designated squad or fireteam leader.

The Weapons Division ensures that the unit is properly armed, equipped, and trained for exercises, operations, or incidents that the PSU may respond to. The Weapons Division consists of a Weapons Officer (WEPO) and multiple Gunner's Mates (GMs).

PSUs are capable of worldwide deployment in national defense regional contingency environments. PSUs conduct layered defensive operations to protect High Value Assets (HVAs) within the protected waters of a port or harbor. Operating environments include operations from shore sites, barges, or other moored platforms (including oil platforms). PSUs typically have enough supplies to operate between 15 and 30 days without resupply. PSUs will normally operate independently but may operate with U. S. Navy Navy Expeditionary Combat Command (NECC). PSUs are capable of conducting continuous boat operations with three or four boats underway simultaneously. An additional boat will be crewed and mechanically ready at all times as a ready response boat. The remainder of the boats may be undergoing maintenance or repair or used for spares. Boat hulls can be expected on station (not including transit and maintenance time) 18 hours per day when more than one boat is undergoing maintenance. During high threat conditions, PSUs are capable of conducting continuous operations with four operational boats for a maximum period of 24 hours.
