World War II soldiers in the Allied and Axis forces were given liberal amounts of amphetamines. Pilots, tank drivers and infantry used Benzedrine, Dexedrine and Methedrine to stay awake for long periods of time and to 'enhance' levels of courage and bravado. Some records indicate that from 1966 to 1969, the U.S. Army dispensed more amphetamine to its troops than the combined total of British and American forces during the entire Second World War. As one veteran of Vietnam put it on an Internet citation, "Take 100 non-aggressive men and give them all enough speed and you end up with the equivalent of 150 men that'll kill anything that moves and if they have to, they'll kill it with their bare hands." Biographers of war crimes committed by troops from various nations throughout the history of modern warfare believe the most heinous acts were the result of the maniacal effects of amphetamines.
Today amphetamine use in the military continues under the current market name of Adderall. Dextroamphetamine is dispensed by the Air Force to keep pilots awake and alert on long missions. Air Force pilots must sign a form called "Informed Consent for Use of Dextroamphetamine as a 'Go Pill' in Military Operations." Although taking the drug is not technically mandatory, as the form states, a refusal to sign the form could result in a commander designating them as 'unfit to fly a given mission'.
