Also known as: corps
Quick Summary
An army corps is a large military unit, typically composed of two or more divisions and auxiliary services. It is the largest regular army formation, with an estimated 50,000 to 300,000 troops. Army corps are commanded by a lieutenant general and can be combined with other corps to form a field army. This organizational structure allows for the coordinated movement and deployment of large numbers of troops under a single leader, as exemplified by Napoleon's use of army corps in his campaigns.123
