SEAL Teams are organized into two groups: Naval Special Warfare Group One (West Coast), and Naval Special Warfare Group Two (East Coast), which come under the command of Naval Special Warfare Command, stationed at NAB Coronado, California. As of 2006, there are eight confirmed Navy SEAL Teams. The original SEAL Teams in the Vietnam War were separated between West Coast (Team ONE) and East Coast (Team TWO) SEALs. The current SEAL Team deployments include Teams 1, 2, 3, 4, 5, 7, 8, and 10.
The Teams deploy as Naval Special Warfare Squadrons or Special Operations Task Forces and can deploy anywhere in the world. Squadrons will normally be deployed and fall under a Joint Task Force (JTF) or a Combined Joint Special Operations Task Force (CJSOTF) as a Special Operations Task Force (SOTF)
A SEAL Team has a Staff Headquarters element and three 40-man Troops. Each Troop consist of a Headquarters element consisting of a Troop Commander (O-4), a Troop Senior Enlisted (E-8), a Targeting/Operations Officer (O-2/3) and a Targeting/Operations Leading/Chief Petty Officer (E-6/7). Under the HQ element are two SEAL platoons of 16 men (2 officers, 14 enlisted SEALs and sometimes 2 enlisted EOD Operators making a platoon of 18); a company-sized Combat Service Support (CSS) and/or Combat Support (CS) consisting of staff N-codes (the Army and Marine Corps use S-codes); N1 Administrative support, N2 Intelligence, N3 Operations, N4 Logistics, N5 Plans and Targeting, N6 Communications, N7 Training, and N8 Air/Medical. Each Troop can be easily task organized into 4 squads or eight 4-man fire teams for operational purposes. The size of each SEAL “Team” with Troops and support staff is approx. 300 personnel. The typical SEAL platoon has an OIC (Officer in Charge, usually an O-3), an AOIC (Assistant Officer in Charge, usually an O-2), a platoon chief (E-7), an LPO (Leading Petty Officer, E-6) and others ranging from E-6 to E-4 (most are E-5). Occasionally there is a "third O". Usually the third O is an O-1 on his first operational deployment. This makes the platoon consist of 3 officers and 13 enlisted personnel. The core leadership in the Troop and Platoon are the Commander/OIC and the Senior Enlisted NCO (Senior Chief/Chief).
Troop core skills consist of: Sniper, Breacher, Communicator, Maritime/Engineering, Close Air Support, Corpsman, Point-man/Navigator, Primary Driver/Navigator (Rural/Urban/Protective Security), Heavy Weapons Operator, Sensitive Site Exploitation, Air Operations Master, Lead Climber, Lead Diver/Navigator, Interrogator, Explosive Ordnance Disposal, Technical Surveillance, and Advanced Special Operations.
