Officer Rank Insignias. Officer ranks in the United States military consist of commissioned officers and warrant officers. The commissioned ranks are the highest in the military. These officers hold presidential commissions and are confirmed at their ranks by the Senate. Army, Air Force and Marine Corps officers are called company grade officers in the pay grades of O-1 to O-3, field grade officers in pay grades O-4 to O-6 and general officers in pay grades O-7 and higher. The equivalent officer groupings in the Navy are called junior grade, mid-grade and flag.
