Greenknight, what about the statement in Washington Post article made by a former combat medic?
"During my year in DaNang, a few combatants urged me to verify small abrasions as “wounds” so they could get a Purple Heart. Each freely admitted trying to acquire Purple Hearts as rapidly as possible to take advantage of the policy allowing those with three Purple Hearts to apply to leave Vietnam early. I refused them. But some went shopping for another opinion. Unfortunately, we had some antiwar physicians in Vietnam who were happy to become accomplices in these frauds."
