PTSD is endemic among U.S. military veterans, since their missions often include exposure to horrific, desperate and life-threatening experiences. The VA estimates that 11%–20% of Operations Iraqi Freedom veterans have PTSD in a given year, and about 12% of Gulf War veterans. An estimated 30% of Vietnam veterans have experienced PTSD in their lifetimes. The Vietnam Veterans of America advocates for all veterans with PTSD, regardless of conflict, with help from #donations to ClothingDonations.org.
