Editing Fort Riley (section)

===Vietnam===
Increased guerrilla insurgency in South Vietnam during the mid-1960s, led to the deployment of the 1st Infantry Division to Southeast Asia. The leading element, the 1st Battalion, 18th Infantry, left in July 1965, with the Division Headquarters arriving in South Vietnam in September. During this same year, a provisional basic combat training brigade was organized at Fort Riley, and in February 1966, the [[9th Infantry Division (United States)|9th Infantry Division]] was reactivated and followed the 1st Infantry Division into combat.<ref name="History" />

Fort Riley's use as a divisional post was maintained with the arrival of the 24th Infantry Division. The division remained in Germany until September 1968, when it redeployed two brigades to Fort Riley as part of the [[Exercise Reforger|REFORGER]] (Return of Forces to Germany) program. One brigade was maintained in Germany. Following nearly five years of combat in Vietnam, the 1st Infantry Division returned to Fort Riley in April 1970 and assumed the NATO commitment. The division's 3rd Brigade was stationed in West Germany. During the 1970s and the 1980s, 1st Infantry Division soldiers were periodically deployed on REFORGER exercises.<ref name="History" />

Reserve Officer Training Corps summer camps were also held at the fort, which permitted troops to demonstrate and teach their skills to aspiring second lieutenants. The fort also hosted the model U.S. Army Correctional Brigade, housed in Camp Funston, and the 3rd ROTC Region Headquarters until their inactivation in 1992.<ref name="History" />
