Explanation: The Nazis used high doses of amphetamines and especially methamphetamine to give their soldiers ‘staying power’ in the field, part of why they overran France - some Nazi tankers were driving and fighting for a week straight without sleep or rest. Lower doses of extended release amphetamines are used in the modern day to treat ADHD. One imagines the occasional lone guy with ADHD and a pervitin pill was sitting under a tree and rethinking some life choices instead.
