Marine Corps Promotion to E-1 Private
To reach the rank of E-1, all Marines must complete Recruit Training, or "Boot Camp", which lasts 13 weeks in either Parris Island, SC, or San Diego, CA. Until graduation, they are Recruits and essentially E-"nothings".
Upon graduation, Marines may be promoted to E-1, E-2, or E-3 depending on several factors. College credits or positive referrals to recruiters can result in automatic promotion. If the Marine was a meritorious JROTC Cadet, Sea Cadet, Young Marine, or Boy or Girl Scout, this may also warrant immediate promotions as put in writing by their recruiters. A Marine may also receive an immediate promotion for being the "honor graduate" of their Recruit Training class.
There are over a dozen ways to immediately promote past E-1 after Basic Training. Speak with a USMC Recruiter for more details. And remember, in the military, nothing is guaranteed unless it is in writing.
