You do realise that USAF pilots were using "pep" pills during the first gulf war?

[Of pilots who were surveyed, 65% used amphetamines during the deployment to the SWA AOR and/or during Operation Desert Storm. Pilots who used amphetamines in air operations described it as "occasional." The most frequent indications for amphetamine use were "aircrew fatigue" and "mission type." Of pilots who used amphetamines, 58-61% considered their use beneficial or essential to operations. ] (https://pubmed.ncbi.nlm.nih.gov/7661838/)
