The Crucible is the defining moment of recruit training. For most, the Crucible will be the first time they reach the limits of their mental, physical, and emotional endurance. They will know that they are capable of much more than they previously believed.
The Crucible consists of 54 hours of intense, physically demanding training, under conditions of sleep and food deprivation. During this time, recruits will be forged in the furnace of shared hardship and tough training that is the time-tried and battle-proven trademark of Marine recruit training. There will be night forced marches, a tough night infiltration movement, a combat resupply event, a casualty evacuation drill, and combat field firing. Any recruit who quits will not bear the title Marine.
Recruits will encounter unique obstacles, each bearing the name of a heroic Marine from our illustrious history, which can only be negotiated with teamwork. Once each obstacle is overcome, the drill instructor mentors the recruits, critiques their efforts, and retells the story of the Marine for whom the obstacle was named, bringing to light how that individual exemplified our core values. . . . . . . Honor, Courage, Commitment.
