In the U.S. Army, Private (PVT) is used for the two lowest enlisted ranks, just below
Private First Class. The lowest rank (officially known as Private E-1 (PV1) and sometimes referred to as recruit but also held by some prisoners after conviction until they are dishonorably discharged) wears no uniform insignia, while the second, Private E-2 (PV2), wears a single chevron. Advancement to the higher rank is currently automatic after six months time in service, but may get shortened to four months if given a waiver (a pay raise may take effect after four months of service, even without advancement to Private E-2 if local commanders decide the private's performance has warranted it).
In the U.S. Marine Corps, Private (Pvt) only refers to the lowest enlisted rank, just below Private First Class. A Marine Corps Private wears no uniform insignia. Most new, non-officer marines begin their military career as a Private.
