Since the Vietnam War, officers' permanent rank is their RA rank. Active duty officers can hold an RA commission and rank and may also hold a higher rank with a USAR commission. Reserve officers hold only a USAR commission, but may serve in either the reserve component or on active duty. That is, all non-permanent ranks (including theater rank, temporary rank, battlefield promotions, etc.) are handled through USAR commissions. Those officers without RA commissions do not have a permanent rank. Enlisted ranks are all permanent RA ranks.
