Book excerpt: The new Spearhead series is designed to look at the cutting edge of war, dealing with units capable of operating completely independently in the forefront of battle. Each volume in the series examines a historic unit's origins, history, organization, order of battle, battle history, insignia and markings. The 21st Panzer Division gained greatest fame in North Africa, but also served in Normandy and on the Russian Front. Each Spearhead title includes an evaluation of the units combat effectiveness as seen by the unit, its opponents and subsequent researchers, and a research section including a bibliography and a listing of museums, websites, re-enactment groups and memorials.
