colonel

A colonel in the United States Army, Marine Corps, Air Force and Space Force, is the most senior field-grade military officer rank, immediately above the rank of lieutenant colonel and just below the rank of brigadier general. Colonel is equivalent to the naval rank of captain in the other uniformed services. By law, an officer previously required at least 22 years of cumulative service and a minimum of three years as a lieutenant colonel before being promoted to colonel. With the signing of the National Defense Authorization Act of 2019 (NDAA 2019), military services now have the authorization to directly commission new officers up to the rank of colonel. The pay grade for colonel is O-6. When worn alone, the insignia of rank seen at right is worn centered on headgear and fatigue uniforms. When worn in pairs, the insignia is worn on the officer's left side while a mirror-image reverse version is worn on the right side, such that both of the eagles' heads face forward, to the wearer's front. Insignia The insignia for a colonel is a silver eagle which is a stylized representation of the eagle dominating the Great Seal of the United States (which is the coat of arms of the United States). As on the Great Seal, the eagle has a U.S. shield superimposed on its chest and is holding an olive branch and bundle of arrows in its talons. However, in simplification of the Great Seal image, the insignia lacks the scroll in the eagle's mouth and the rosette above its head. On the Great Seal, the olive branch is always clutched in the eagle's right-side talons, while the bundle of arrows is always clutched in the left-side talons. The head of the eagle faces towards the olive branch, rather than the arrows, advocating peace rather than war. As a result, the head of the eagle always faces towards the viewer's left. Some colonel eagles from the 1920s to the 1950s faced the arrows, though this is no longer done. The full-sized colonel eagle is 3/4 inches tall and inches in diameter from the tips of each wing.
