SEAL Team 4 is an operational naval special warfare unit of the United States Navy specializing in maritime, littoral, and riverine special operations. It operates alongside joint and coalition units such as United States Special Operations Command, Joint Special Operations Command, United States Marine Corps Forces Special Operations Command, and international partners including Royal Navy and Special Air Service. The unit has been deployed in theaters ranging from Vietnam War support roles to counterinsurgency and counterterrorism campaigns in Iraq War, War in Afghanistan (2001–2021), and global maritime security missions.

History

SEAL Team 4 traces roots to the Naval Combat Demolition Units and Underwater Demolition Teams of World War II, evolving through the establishment of SEAL Teams in the 1960s during the Vietnam War. Elements have supported operations linked to major events such as Operation Eagle Claw, Operation Urgent Fury, Operation Just Cause, Operation Desert Storm, and the post-9/11 campaigns including Operation Enduring Freedom and Operation Iraqi Freedom. The unit has been referenced in after-action analyses alongside engagements like the Battle of Mogadishu (1993), Operation Red Wings, Operation Anaconda, and multinational efforts such as Operation Atalanta and Operation Ocean Shield. SEAL Team 4 capacity expanded during the Global War on Terrorism and integrated lessons from incidents like the Maersk Alabama hijacking response and maritime counter-piracy patrols in the Gulf of Aden.

The unit is organized into platoons and detachments comparable to other SEAL Team organizations and coordinates with commands such as Naval Special Warfare Command, United States Special Operations Command Europe, United States Central Command, and United States Africa Command. Its internal structure parallels elements in SEAL Team 6 task units and shares doctrine with United States Army Special Forces, Delta Force, 9th Special Forces Group (Airborne), and British Special Boat Service. Support functions liaise with agencies including Central Intelligence Agency, Federal Bureau of Investigation, National Security Agency, and multinational partners like NATO and European Union Naval Force. Logistics and basing are managed through installations such as Naval Air Station North Island and forward expeditionary nodes in regions like Bahrain, Djibouti, Guam, and Diego Garcia.

SEAL Team 4 conducts direct action, special reconnaissance, hostage rescue, and counterterrorism missions in littoral environments and riverine settings; operations have intersected with campaigns like Operation Phantom Fury, Operation Moshtarak, Operation Khanjar, and interdictions in the Strait of Hormuz and Horn of Africa. The unit has participated in maritime interdiction operations supporting initiatives such as Combined Task Force 151, counter-narcotics missions tied to Operation Martillo, and security cooperation activities with partners including Japan Maritime Self-Defense Force, Australian Defence Force, Canadian Special Operations Forces Command, French Navy, German Navy, Indian Navy, and Israeli Navy. Notable mission environments include urban centers like Baghdad, Kandahar, Basra, and coastal hotspots like Somalia and the Philippines (2002-present insurgency). SEAL Team 4 has also supported disaster response coordination alongside agencies such as United States Agency for International Development during crises affecting locations like Haiti and Philippines.

Personnel are selected through pipelines including Basic Underwater Demolition/SEAL (BUD/S), SEAL Qualification Training, and mission-specific courses such as Special Operations Combat Medic Course, Army Ranger School, SERE school, and advanced language or cultural training with Defense Language Institute. Training integrates instruction from institutions like Naval Special Warfare Center, National Defense University, Joint Special Operations University, and collaborative exercises with units such as USSOCOM West affiliates, Royal Australian Navy clearance divers, and Royal Netherlands Marine Corps forces. Preparation emphasizes amphibious warfare doctrines derived from historical studies of Guadalcanal Campaign, D-Day landings, Korean War riverine actions, and modern urban combat lessons from Battle of Fallujah and Siege of Marawi.

SEAL Team 4 employs maritime platforms and systems including Mk V Special Operations Craft, Rigid-hulled inflatable boat, SEAL Delivery Vehicle, MH-60 Seahawk, MH-47 Chinook, and rotary assets like MH-6 Little Bird in joint operations with United States Air Force Special Operations Command. Small arms and mission equipment include variants of the Mk 18 Mod 0, M4 carbine, SR-25, HK416, MP7, FN SCAR, and sniper systems such as the M110 Semi Automatic Sniper System. Divers use systems like closed-circuit rebreathers, underwater navigation suites, and diving gear sourced via Naval Sea Systems Command procurement channels, while reconnaissance relies on ISR platforms including MQ-9 Reaper, RQ-11 Raven, ScanEagle, and maritime sensors integrated with United States Fleet Forces Command networks. Communications and cyber capabilities are coordinated with Cyber Command and satellite assets through United States Space Force links.

Operators from the unit have included decorated individuals recognized with honors such as the Medal of Honor, Navy Cross, Silver Star, Bronze Star Medal, and Purple Heart for actions in campaigns like Operation Red Wings and Iraq War. SEAL Team 4 members have been cited in unit awards like the Presidential Unit Citation, Joint Meritorious Unit Award, and Navy Unit Commendation. The unit’s personnel have trained with or been mentioned alongside notable figures and units such as Richard Marcinko, Chris Kyle, Marcus Luttrell, Robert O'Neill, Matt Bissonette, Jocko Willink, Kyle Carpenter, SEAL Team Six (DEVGRU), United States Navy SEALs Hall of Fame, and allied counterparts like SAS Regiment members. Career paths often lead to instructional roles at Naval Special Warfare Center and positions within interagency task forces involving CIA Special Activities Center.
