Navy SEALs Training

Each SEAL Team is commanded by a Navy Commander (O-5), and has a number of operational SEAL platoons and a headquarters element.
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 16–20 men (two officers, 14–16 enlisted SEALs and sometimes two enlisted EOD Operators making a platoon of 18–20); 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 four squads or eight 4–5 man fire teams for operational purposes. The size of each SEAL “Team” with Troops and support staff is approximately 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 Operations NCO/LPO (Leading Petty Officer, E-6) and other operators E-5 to E-6. 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.
