Army or Marine...begins at Colonel. Navy or Coast Guard..begins at Captain. Field or senior officers. Field officers, also called "field-grade officers" or "senior officers," are officers who typically command units that can be expected to operate independently for short periods of time (i.e., infantry battalions, cavalry or artillery regiments, warships, air squadrons). Field officers also commonly fill staff positions of superior commands. The term "field(-grade) officer" is primarily used by armies and marines; air forces, navies and coast guards generally prefer the term "senior officer." The two terms are not necessarily synonymous. Typical army and marine field officer ranks include Colonel (pronounced /ˈkɜrnəl/), Lieutenant Colonel, Major and, in the British army, Captains holding an adjutant's appointment. In many Commonwealth countries the field rank of Brigadier is used, although it fills the position held by Brigadier General in other countries. Naval and coast guard senior officer ranks include Captain and Commander. In some countries, the more senior rank of Commodore is also included. In others Lieutenant-Commanders, as equivalents to army and marine Majors, are considered senior officers. Commonwealth air force senior officer ranks include Group Captain, Wing Commander, and Squadron Leader, where such ranks are still used. http://en.wikipedia.org/wiki/Military_rank Jan 03 11, 5:43 PM
