I created this excel file to track and facilitate PBE-Mail of the AHGC Battle of the Bulge-1981. The German player inputs his 16-AM movement for each counter available in his OB and resolves battles. The file allows for advances/retreats and the new hex locations for both German and US pieces. The US player then takes his 16-AM turn in the same worksheet. The 16-AM tab is copied to make the 16-PM turn and the procedure is repeated. Allows for assignment of Support Fire artillery and Air Support and marking/tracking the counters that are eliminated as the Germans advance. Enjoy.
