Third Phase, the land warfare phase, is seven weeks long and teaches the class basic weapons, demolitions, land navigation, patrolling, rappelling, marksmanship, and small-unit tactics. For the final three and a half weeks of training, the class goes to San Clemente Island, about 60 miles from Coronado, CA. On the Island, the class practices the skills they learned in Third Phase. Men who make it to Third Phase have demonstrated extraordinary commitment to becoming SEALs. Few leave BUD/S during this phase.
