This is the Army Lists book for the European fronts of World War I. You will need the Contemptible Little Armies rulebook in order to use these lists. Some of the armies are broken down by years as the armies were organized differently during those time frames. Along with the Lists, are several pages of quick references on the armies at the back of the book. So for those quick, pick-up games, you will not need to write out your lists. —description from the publisher
