Although volumes have been written about the invasion of Normandy, very little has ever been printed on the specialized units that were developed specifically for the landings. Jonathan Gawne, the well-known American military historian specialising in the development of uniforms for the US Army, tells the story of these units, and how they fit into the overall invasion plan. Spearheading D-Day examines each unit for not only its mission in the landings, but also its organisation, uniforms, insignia and equipment.
