Book Cover - Soldiers under the sign of the corpse's head

This is a book which is a kind of exhausting lexicon about all military units, as well as police around the world, national liberation movements, etc., which were distinguished by the sign of a skull. Although the military skull mark is usually associated with the period of World War II and is attributed to the ominous symbolism of the SS, it must be known that almost all European armies, except for Swiss and Norwegian, have been using it for many centuries.
