 Since October 2006, the U.S. Army's 1st Infantry Division, based at Fort Riley, Kansas, was responsible for training all transition teams for service in Iraq and Afghanistan.Previously, advisor teams had been trained at several U.S. Army installations, most notably Fort Carson, Colorado; Camp Atterbury, Indiana; Fort Hood, Texas; and Camp Shelby, Mississippi.However, in early 2006, the U.S. Army decided to consolidate all training at Fort Riley in order to standardize and improve training for that critical mission.
