Ranger School

The United States Army Ranger School is an intense 61-day combat leadership course oriented towards small-unit tactics. It has been called the "toughest combat course in the world" and "is the most physically and mentally demanding leadership school the Army has to offer". The course is conducted in various locations. Training in the Benning Phase occurs in and around Camp Rogers and Camp Darby at Fort Benning, Georgia. Training at the Mountain Phase is conducted at Camp Merrill, in the remote mountains near Dahlonega, Georgia. The Florida Phase is conducted at various locations near Camp Rudder, Eglin Air Force Base, Florida. The Desert Phase—conducted initially at the White Sands Missile Range in New Mexico, and later relocated to Dugway Proving Ground, Utah and Fort Bliss, Texas—was eliminated in 1995.

The United States Army Ranger School is not organizationally affiliated with the 75th Ranger Regiment. Ranger School falls under control of the United States Army Training and Doctrine Command as a school open to most male members of the United States Army; while the 75th Ranger Regiment is a Special Operations warfighting unit organized under the United States Army Special Operations Command. The two share a common heritage and subordinate battalions common lineage, and Ranger School is a requirement for all officers and NCOs of the 75th Ranger Regiment. Although Ranger School is effectively closed to female applicants due to the Combat Exclusion Laws pertaining to assignment to Ranger-coded positions within the Combat Arms of the United States armed forces, as of 2012, the U.S. Army's senior leaders are considering opening the school to women.
