SEALs go through some of the most intense and selective training in the world, with usually around a 90 percent attrition rate. Those who make it are very mentally and physically tough people. The 6 month long basic training involves running in sand, laying in 50 degree ocean water until early stages of hypothermia, obstacle courses, endless workouts, diving, shooting, and explosives training. This is known as BUD/S, or Basic Underwater Demolition/SEAL Training, and takes place on the beaches of Coronado, California.

After BUD/S, or Basic Underwater Demolition/SEAL Training, those who have made it continue on to Military Parachuting school in Fallon, Nevada. Here the students learn free fall parachuting.

Next, they continue on to SQT, or SEAL Qualification Training, a 2 month course that teaches advanced shooting tactics and combat diving.
