Almost every country in the world has its elite units. These are the men and women who perform operations no regular soldiers will touch, who go deep into enemy territory to sabotage, attack, rescue, and observe. This book looks at life in five of the most prestigious military units - the U.S. Airborne Forces, the Israeli Parachute Corps, Russian Spetsnaz forces, the British SAS, and the Australian SAS. Each force has its history explored to show why they are respected and feared by their enemies, and a special chapter looks at the weapons and equipment of these incredible units.
