 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.The Marines Corps initially coordinated all ETT training through the SCETC (Security Cooperation Education and Training Center) in Quantico Virginia and later, in 2008, SCETC established the Advisor Training Group in Twentynine Palms California.
