Corps, << kawr, >> is an army unit consisting of two or more divisions. The term corps comes from a Latin word meaning body. A corps is normally composed of about 50,000 to 100,000 soldiers. Most corps are commanded by a lieutenant general. A corps can conduct major military operations. The word corps also refers to the U.S. Marine Corps and to such branches of the U.S. Army as the Corps of Engineers and the Signal Corps. See also Army, United States (table: Army levels of command).
