United States Marine Corps Recruit Training (commonly known as "boot camp") is a 13-week program, including in & out-processing, of recruit training that each recruit must successfully complete in order to serve in the United States Marine Corps. The only Marine Corps recruits not required to undergo training are those selected for the United States Marine Band. Upon passing an audition and satisfying security and physical fitness requirements, they are granted the rank of Staff Sergeant and assigned exclusively to the band for a four-year enlistment.
