Battle Rosters. Battle rosters are maintained at battalion level and below to track key training information on selected mission essential systems (such as tanks, howitzers, automated command and control systems, forklifts, etc.). They track such pertinent training data as crew stability and manning levels, and qualification status. A key aspect of battle rosters is the designation of qualified back-up operators or crewmembers assigned in other positions in the organization. During the execution of training, battle rostered crewmembers train with their designated crewsat available opportunities. Commanders must discipline the battle roster system.
