From the author-> Background Information: The BAPS booklet is 75 spiral-bound pages with a card-stock cover and two, letter-sized chart cards, one for infantry actions and one for vehicles and artillery. In designing BAPS, I designed and threw away at least two complete rules systems. The result is something I am proud of -- except the title. Some day I will come up with a title that implies both infantry and armored skirmishes. Period covered: The rules were designed for WWI to the present; however, they work equally well for any "smokeless powder" era, including the Spanish Civil War, Mexican Punitive Expedition, Spanish-American War, and Philippine Insurrection. The primary focus is WWII, and most of the order of battle information, vehicle data charts, and scenarios are aimed at this period.
