How Long Is Basic Training in the Marines? The United States Marine Corps is known as America's first line of defense. To become a Marine, you must be at least 17 years old at the time of enlistment and hold a high school diploma. You must also complete 12 weeks of intense training.
An enlisted Marine must serve for four years to receive an honorable discharge after they enter basic training (this is pretty universal among the U.S. Military.) Boot camp lasts 3 months and the time spent there does count toward the day when you get out. The School of Infantry is another few months after that. After this a Marine will join his unit. The units are usually at a point preparing for their next deployment.
