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.
Marine Corps training is legendary, but the recruit training that exists today didn't begin until 1911. Major General William P. Biddle, the 11th Commandant of the Marine Corps, formalized and intensified the training, raising the bar for what it takes to become a United States Marine.
