The world's combat swimmer units deserved such a book. With a wealth of photographs and documents ? many of them never published before ? Shadow Warriors features the historical record and current operational life of the German Kampschwimmers and the French Naval Commando Hubert, not to forget the first unit of all in this brend, the Italian Incursori which gave birth to this highly specific combat skill. A full colour book also featuring line drawings and profiles of light submarine equipment used by these very discreet elite units.
