Battle Command and Sustainment Support System

Within the Army Battle Command System, the Battle Command and Sustainment Support System (BCS3) , formerly the Combat Service Support Control System (CSSCS) is the logistical support component. It is also used by the U.S. Marine Corps.

Among its capabilities are allowing commanders to specify which supply items are of importance to them, and maintaining awareness of those items in a Commander’s Tracked Item List (CTIL). During operations, the commander or logistics staff specify their CTIL from the national-level Baseline Resource Item List (BRIL).
