Squad Leader is a tactical level board war game originally published by Avalon Hill in 1977. It was designed by John Hill and simulates on infantry combat in Europe during World War II. One of the most complex war games of its time, Squad Leader is the natural extension of the trend towards greater realism (and hence complexity) initiated by several earlier games, including Avalon Hill's own PanzerBlitz and Panzer Leader. Those two earlier games were slightly larger in scope, with counters representing platoons and map hexes measuring 250 metres across, compared to Squad Leader's 40 meter hexes and squad sized units. The original Squad Leader was produced in time to debut at Origins 1977. (The original print run of 2,500 copies had purple boxes which have become collectors' items.) Avalon Hill sold well in excess of 100,000 games of Squad Leader, making it one of the most successful war games ever made. Combined with the sales of Advanced Squad Leader, its sales totaled over 1 million copies by 1997. Gameplay Pieces in Squad Leader represent regular squads (rated for firepower, range and morale), weapon and vehicle crews, elite squads (with high firepower and morale but shorter range - used to represent paratroops or combat engineers armed with sub-machine guns), individual leaders, support weapons, and vehicles. The original game contains counters representing the German, Russian and American armies. Russian troops are portrayed as poorly armed (and with poor quality radios, making it very difficult for them to summon artillery support) and with relatively fewer leaders, but with the capacity to become "berserk" in combat (a capacity shared in later expansions by SS troops). US troops are shown as having unusually high firepower (representing larger squads, using the Browning Automatic Rifle - unlike other nationalities who have separate counters for light machine guns), but with slightly lower base morale than German or Soviet troops, representing the supposed greater tendency of more individualistic Americans to break from their orders or the group under fire - however, American troops are easier to rally under fire, as they were exempt from the usual penalty ("desperation morale") paid by broken squads in these circumstances. British troops, when eventually added to the game system, are shown as largely similar to the Germans, albeit with somewhat inferior equipment. The mapboards are divided into hexagonal grids with each hex said to represent 40 metres of terrain, the result
