The advent of the “Special Operations” Weapon known as a SADM – or Special Atomic Demolition Munition was first fielded in the 1960s, was a primary deployment device of The “Green Light” Teams. These Military Units were primarily composed of US Army Special Forces, Marine Force Recon and Naval UDT/Frogmen (the precursor to The Navy Seals). The Mission of The “Green Light” Teams, were to infiltrate Enemy Territory and deploy specially designed Atomic Munitions which could be carried on the back of an average Soldier. The average Device carried was 15-inches long and 10-inches in diameter. The SADM weighed 50-pounds and was carried in a specially built, harness backpack. The average tactical yield of The SADM was between 1 and 10-Kilotons. Green Light Teams parachuted into Enemy Territory and proceeded to a prearranged target. The SADM was placed and activated. Fortunately, no SADM Green Light Teams ever had to deploy. However, The SADM Training School and the deployment of these kind of Nuclear weapons would continue until 1985.
