This study examines how leaders of tactical units can use the Army's Lesson-Learned System (ALLS) to their best advantage. The ALLS was established to identify, collect, analyze, and then disseminate lessons from contingency operations and training exercises throughout the force. This system is central to learning in units and the Army. While the guidance for these procedures is very clear for the overarching Army program, very little information is provided to leaders of tactical units on how they can best support the program and leverage lesson learning in their organizations. Analysis revealed that lesson learning as it is defined in AR 11-33, The Army Lesson Learned System occurs on an ad hoc basis in tactical units. There are several reasons for this shortfall. Nevertheless, the Army's lesson-learned program, as it pertains to tactical units, needs to be reevaluated. It is recommended that specific guidance on how to establish learning programs be provided to leaders of tactical units in both AR 11-33 and in training doctrine. In the absence of doctrine, leaders must take proactive steps to establish learning programs in their units.
