Navy SEAL trainees practice room entry and clearing techniques.
Close Quarters Battle (CQB) is a vital part of SEAL training.
Navy SEALs are a component of United States Naval Special Warfare Command.
They specialise in direct action raids, special reconnaissance and counter terrorism operations.
SEAL training takes over a year and includes a 24-week Basic Underwater Demolition/SEAL school (BUD/S) and a 28-week SEAL Qualification Training (SQT).
Once assigned to a SEAL Platoon, SEALs undergo SEAL Troop (TRP) Training.
