<P> However, the rivalry between MCRDs Parris Island and San Diego is much more pronounced . Marines trained at San Diego are often referred to as "Hollywood Marines" because of the base's location in Southern California . Marines trained at Parris Island are sometimes referred to as "Swamp Dogs" because of the large amount of marshland surrounding the base and more derisively known as "PIGs" (an acronym for Parris Island Graduates) and "Hump Waivers" because the terrain there is significantly less hilly than that of the West Coast . Marches with a pack are often called "hump" s . </P> <P> Boot camp is a twelve - week cycle of training, beginning with a receiving phase of in - processing or "forming", followed by three numbered phases . Each phase includes intensive education and training on various topics essential for military life . Each phase consists of a predetermined number of training days, these are counted in the training matrix as "T1", "T2", up to "T70" which is Graduation Day . </P> <P> The initial period of Marine Corps Boot Camp is called the Receiving Phase, which begins as the new recruits are on the bus en route to their recruit Depot . They are "greeted" by a drill instructor, who acquaints them with the Uniform Code of Military Justice, to which they are now subject . Disembarking from the bus, they line up on rows of yellow footprints painted on the concrete which is their first formation and learn how to stand at attention . </P> <P> The recruits are given the opportunity to phone their next of kin and inform them of the recruit's safe arrival, then are searched for contraband . They are issued utility and physical training uniforms and toiletries . From here, the males receive their first military haircut, where they are left essentially bald . Females are instructed in the authorized hairstyling, which allows hair to be short enough to not touch the collar or in a bun . </P>
