The U.S. Army Officer Candidate School is organizationally designated as "3rd Battalion, 11th Infantry Regiment, 199th Infantry Brigade". It was redesignated from the 3rd Battalion, 11th Infantry Regiment in June 2007. It is a subordinate unit of the Maneuver Center of Excellence (MCoE) also headquartered at Fort Benning. As of July 2014 the battalion has five training companies and a Headquarters Company in operation, designated HHC, Alpha, Bravo, Charlie, Delta and Echo, each of which can conduct one class at a time, with a maximum of 160 candidates being trained in each class. Generally, only Alpha thru Delta are used, but if there are sufficient numbers of students, Echo company will be opened-up as well. HHC serves as the "holding" company for brand new candidates going thru their in-processing or for injured candidates who are recuperating from their injuries. Those who recuperate from injury are often "recycled" into the next class. Every three weeks a class graduates and another one is started.
