In boot camp, Marine recruits must endure a 54-hour training event under intense mental and physical distress.

During the exercise, recruits will hike over 45 miles while taking on several obstacles that require strong problem-solving and teamwork. Every moment of the event is highly structured, planned well in advance, and done under strict Marine supervision. Toward the end of their days-long test, each recruit must negotiate one of the toughest hikes up one of the steepest hills in Camp Pendleton, best known as the "Reaper." This is the final test before earning the title of U.S. Marine.

As darkness still blankets the recruits outside their berthing area, drill instructors blare their high-decibel horns to awaken those who are about to experience the Reaper. The young troops quickly pack up their heavy gear and begin the last 9.7-mile hike of basic training as they approach the 700-foot-tall hill.

As each recruit ascends the hill, the fatigue of spending days on minimal rations and little sleep sets in. Each of the recruits must now motivate one another to overcome the struggle and make it up the tall hill. This final hike pays homage to the brave Marines who willed themselves to the top of Mount Suribachi, securing the area from their Japanese enemy.

This final test of fortitude is just the beginning of a long career for these soon-to-be Marines, as life in the Corps is just as tough as the last 13-weeks they've endured. Pushed by an overwhelming amount of motivation, recruits surpass obstacles they didn't know even existed before boot camp.

Recruits approach this final challenge, charging as hard as they can, screaming out war cries, and pushing their bodies beyond limits. Before they know it, they've reached their ultimate goal: becoming a United States Marine.

Overcome with emotion, the young Marines open their palms to receive their Eagle, Globe, and Anchor from a once-demanding drill instructor, who now calls them a brother.
