There are so many drugs used in wars. In addition to the standard stimulants and painkillers, some Russian soldiers in Bucha were using ED pills (viagra) in their campaign to denazify elderly people and children.
In 2014, the U.S. military distributed almost $85 million of Viagra to their ranks. More than 100,000 prescriptions to active-duty soldiers. I get what you are implying but there is usually a rational reason when armies are distributing ED medication.
