Private

In both the Union Marine Corps and the Union Army the rank of Private (Pvt) refer to the lowest enlisted rank, just below the rank of Private First Class (PFC.)

Most individuals enlisting in either the Marine Corps or the Army enlist as a Private, although under certain conditions

Advancement to the PFC is automatic for new enlistees after six months time in service, but may get shortened to four months if given a waiver at the end of Boot Camp.
