This book covers the organization, tactics, weapons, equipment, orders of battle, and uniforms of official and unofficial units, from early raiding parties to formal assault battalions. Rare photos depict badges and insignia not previously known, while primary documents describing regulations and training are provided in their entirety. New information on the origin of shock tactics is presented, gleaned from German archives and not previously published in English. Specific operations on all fronts are included, along with extracts from German army manuals for shock-troop arms such as flamethrowers, mortars, machine guns, grenade launchers, assault artillery, and tanks.
