U.S. Army Center for Army Lessons Learned

The Center for Army Lessons Learned (CALL) is an agent for change focused on the collection, analysis, dissemination, integration, and archiving of new concepts; tactics, techniques, and procedures (TTP); and solutions throughout the Army from the tactical through theater/strategic levels of war. CALL is forward deployed around the globe and provides joint, interagency, intergovernmental, and multinational (JIIM) forces with historic and emerging observations, insights, and lessons (OIL). The support provides valuable TTP to deployed and follow-on forces and helps improve the warfighting capabilities of the Army. CALL is a multi-media based operation that disseminates these lessons and other related materials through a variety of print and electronic media, including their web site.

After the Army’s experience in Operation Urgent Fury, the Chief of Staff of the Army, General John Wickham, tasked the Army Studies Group to conduct an analysis of the Army’s ability to adapt forces to local conditions in combat. On June 15, 1984 the Army Studies Group, headed by Colonel Wesley Clark, proposed a system for capturing lessons learned and adapting units for combat. The Chief of Staff of the Army quickly approved the recommended approach. CALL was officially stood up on August 1, 1985 as a directorate of the Combined Arms Training Activity (CATA) located at Fort Leavenworth, KS.
