In the United States Army (USA), U.S. Marine Corps (USMC), U.S. Air Force (USAF), and U.S. Space Force (USSF), captain (abbreviated "CPT" in the USA and "Capt" in the USMC, USAF, and USSF) is a company-grade officer rank, with the pay grade of O-3. It ranks above first lieutenant and below major. It is equivalent to the rank of lieutenant in the Navy/Coast Guard officer rank system and should not be confused with the Navy/Coast Guard rank of captain. The insignia for the rank consists of two silver bars, with slight stylized differences between the Army/Air Force version and the Marine Corps version.
