BUD/S Training: Combat Diving and Land Warfare
Since much of a SEAL's work is done underwater, SCUBA (self-contained underwater breathing apparatus) and combat diving are top priorities for training.
SEALs train extensively for seven weeks to become combat swimmers and learn open and closed-circuit diving.
During land-warfare training, SEALs train for seven weeks in basic weapons, demolitions, land navigation, patrolling, rappelling, marksmanship and small-unit tactics. They are also trained to react to sniper attacks and to use "edged" weapons such as knives and other blades. SEALs must be able to drive any vehicle and be skilled in high-speed and evasive driving techniques. Hand-to-hand combat is also taught during this phase of training.
To be prepared for anything, they are taught the tactics small units must use, including handling explosives, infiltrating enemy lines, recovery (snatch-and-grab) techniques, and proper handling of prisoners. SEALs must also be able to survive in extreme environments and provide medical treatment (field medicine).
