| Modafinil | Militaries of several countries are known to have expressed interest in modafinil as an alternative to amphetamine – the drug traditionally employed in combat situations where troops face sleep deprivation, such as during lengthy missions. The French government indicated that the Foreign Legion used modafinil during certain covert operations. The United Kingdom's Ministry of Defence commissioned research into modafinil from QinetiQ and spent £300,000 on one investigation. In 2011, the Indian Air Force announced that modafinil was included in contingency plans. In the United States military, modafinil has been approved for use on certain Air Force missions, and it is being investigated for other uses. As of November 2012, modafinil is the only drug approved by the Air Force as a "go pill" for fatigue management. The use of dextroamphetamine (a.k.a., Dexedrine) is no longer approved. | Yes | Confirmed testing | Yes | Yes | Yes | Yes |

## Historic

* Alcohol has a long association of military use, and has been called "liquid courage" for its role in preparing troops for battle, anaesthetize injured soldiers, and celebrate military victories. It has also served as a coping mechanism for combat stress reactions and a means of decompression from combat to everyday life. However, this reliance on alcohol can have negative consequences for physical and mental health. Military and veteran populations face significant challenges in addressing the co-occurrence of PTSD and alcohol use disorder.
* Benzedrine was claimed to have been administered by Allied forces during WWII, esp. by the US
** Germany and Japan used methamphetamine.
* Fenethylline (trade name Captagon) has played a role in the Syrian civil war. The production and sale of fenethylline generates large revenues which are likely used to fund the purchase of weapons, and fenethylline is used as a stimulant by combatants. Poverty and international sanctions that limit legal exports are contributing factors. Since the fall of the Assad regime the new Syrian transitional government has ordered the cessation of the drug trade, and production has reportedly been reduced by 90%.
* Methamphetamine ("Panzerschokolade", "Pervitin") during WWII by Nazi Germany
** Fliegerschokolade [de] was the eponymous name that the Luftwaffe are claimed to have used.
** D-IX was a combination of Methamphetamine, Oxycodone, and Cocaine that was produced in 1944 but could not be mass produced before the war ended. It was part of a future generation of "pep pills" for the German military and was tested on concentration camp prisoners.
