These rules have been designed so that players can fight typical small battles between European Colonial armies and their opponents during the period between 1875 and 1910. They use a gridded battlefield, which removes the need to measure both move distances and weapon ranges, thus speeding up the whole process of fighting a wargame. It also removed any doubts or possible disputes as to whether or not a unit has moved too far or if it is in range or not. They also incorporate simple combat resolution systems that likewise speed up game play. The armies needed to fight battles with these rules are small by most wargames standards. This means that you can 'raise' lots of small armies rather than a couple of big ones.
