Osprey Men-at-Arms №139. Bruce Quarrie. German Airborne Troops 1939-45

Osprey Publishing, 1983. — 49 p. — ISBN: 0850454808.A strong enemy force to one's rear disrupts supplies and communications and makes one more vulnerable to an attack from the front. It also has a major psychological impact. To an aggressor the value of airborne troops, used properly, far outweighs their numerical strength.
