DBMM Army Lists Book 4 is the final volume in the series of publications providing detailed guidance on the structure and organization of ancient and medieval armies for use with the De Bellis Magitsrorum Militum (DBMM) wargame rules. The result of extensive research, Book 4 spans the high medieval period from 1071 AD to 1515 AD and covers armies from Europe, Asia, the Americas, the Middle East and Africa. Each of the 85 army lists details troop types and numbers to allow the wargamer to recreate realistic armies that faithfully reflect the composition of their real-life prototypes. Accompanying each list are historical notes providing in depth commentary on the troops involved along with information on naval units, terrain and climate. A must for competition games, DBMM Army Lists Book 4 also provides an invaluable general reference source for the troop types and organization of the armies of the period.
