The U.S. army is structured roughly:
See also regiment for cavalry units.
The Army is organized by function. Combat forces include Infantry, Armor, Cavalry, and Special Operations Forces. Combat support troops include Artillery, Army Aviation[?], Army Logistics[?], Army Medical Corps[?], Army Transportation[?], Army Ordnance[?], Adjutant General's Corps[?],Signal Corps[?], and the Judge Advocate Generals Corps[?].
The Officer Corps provides leadership and managerial functions, and is composed of Company Grade officers (Second Lieutenant - gold bar, First Lieutenant - silver bar, Captain - two silver bars), Field Grade officers (Major - gold oak leaf, Lieutenant Colonel - silver oak leaf, Colonel - silver eagle), and General officers (Brigadier General - one star, Major General - two stars, Lieutenant General - three stars, General - four stars). Officers receive a "Commission" assigning them to the Officer Corps by act of Congress.
The Warrant Officer Corps is largely composed of highly trained specialists in certain select areas who must have a rank commensurate with their responsibility.
The primary sources for Warrant Officers are the various Warrant Officer Training Programs at military posts and installations around the United States.
The Non-Commissioned Officer Corps[?] (or NCO Corps) is the first line of leadership for the Enlisted[?] members of the Army, and includes the ranks of Corporal (two stripes up), Sergeant (three stripes up), Staff Sergeant (three stripes up and one down), Sergeant First Class (three stripes up and two down), Master Sergeant (three stripes up and three down), First Sergeant (which holds the same enlisted pay grade as Master Sergeant, but which carries extra administrative duties - three stripes up and three down with a lozenge in the center), Sergeant Major (three stripes up and three down with a star in the center), Command Sergeant Major (three stripes up and three down with a wreathed star in the center) and Sergeant Major of the Army (of whom there is only one, and who advises the Chief of Staff of the Army on matters relating to Enlisted personnel - three stripes up and three down with a centered eagle accompanied with two stars).
Training for Non-Commissioned Officers takes place at any of the various NCO training centers around the world.
It should be noted here that it is the outstanding quality of the Non-Commissioned Officer ranks which has largely built the excellent reputation of the United States Army. Until relatively recent history, most countries depended upon their officer corps to micromanage strategy, tactics and virtually every other aspect of military operations. With the development of the NCO Corps, the United States Army took a giant step toward utilizing the skills, intelligence, adaptability and independence of its citizens during times of conflict. The confidence and esteem in which the Officer Corps holds the NCOs which serve in the United States Army is based upon hard-won combat experience. This experience has repeatedly shown that rank is no indicator of leadership ability, and that leaders will emerge during times of hardship and conflict. Many military historians have held that this is the true strength of any military organization which serves a democracy.
Enlisted ranks are Private (no rank insignia), Private Enlisted Grade 2 (one chevron pointing up), Private First Class (one stripe up and a curved stripe (a rocker below), and Specialist (which is the same Enlisted Grade as Corporal, but which requires technical leadership skills, as opposed to the combat leadership skills required of Corporal -a dark green patch with an eagle centered).
Training for enlisted soldiers usually consists of Basic Training, and Advanced Individual Training in their primary Military Occupational Specialty (MOS) at any of the numerous MOS training facilities around the world.
All members of the Army must take an oath upon being sworn in as members, swearing (or affirming) to "protect the Constitution of the United States from all enemies, both foreign and domestic." This emphasis on the defense of the United States Constitution illustrates the concern of the framers that the military be subordinate to legitimate civilian authority.
