While located at Camp Pendleton, Edson Range is organized as an annex of the Marine Corps Recruit Depot, San Diego (MCRD) and serves as the rifle qualification range where Marine recruits receive field and rifle training during boot camp. Two weeks of marksmanship training followed by one week of infantry field skills take place at Edson Range, which is known as "up north" by recruits and drill instructors alike (the Recruit Depot in San Diego being "down south"). The Crucible, a three to four day combat simulation with little food or sleep also takes place here.
Marine recruits undertake two different courses of fire while learning how to use the M16 series rifle. During their first week of weapons training, recruits learn in a classroom setting with instruction coming from a PMI (Primary Marksmanship Instructor). On the second week, recruits will go to one of the three Known Distance (KD) ranges to fire Table 1A, their first course of fire. The three live fire ranges aboard Edson Range where Table 1 is fired are the "World Famous" Bravo Range, Charlie Range, and Delta Range. The week after qualifying on Table 1 is spent on Alpha Range where the recruits will fire Table 2 which is the introduction to the Marine Corps' Combat Marksmanship Program.
