Marine Corps Recruit Depot — San Diego

Same DIs, same screaming, same transformation — just with better weather and a view of the runway at Lindbergh Field to remind you the civilian world exists without you. They call West Coast grads "Hollywood Marines" and East Coast will never let you forget it. Thirteen weeks of the hardest basic training in the U.S. military, palm trees notwithstanding. The Crucible doesn't care about your zip code.
