Marine Boot Camp is the longest of all the United States Armed Forces, and considered to be the toughest. It consists of more than 70 “training days” in a period of 13 weeks.
Marine Corps Recruit Training consists of close order drill, rifle marksmanship, Marine Corps Martial Arts instruction, and classroom instruction on history, customs and courtesies, and a demanding physical fitness regimen.
It’s culminating event, the Crucible, is a 54 hour event where recruits encounter 32 obstacles over a course of 40 miles. During the three day period, recruits only get four hours of sleep and three meals.
