Advanced Squad Leader, or simply ASL, is a tactical wargaming system capable of simulating almost any small unit action from the World War II. ASL is played on a set of geormorphic mapboards that are divided into hexagons. Thanks to the efforts of individual scenario designers, and offerings from third-party retailers, there are now well over 2,000 scenarios available for the Advanced Squad Leader system. Battles ranging from Anzio to Guadalcanal are represented with new scenarios being released all the time.
