Dan Gannon, from Mingo, Iowa, served in Vietnam from 1969-1970 as a platoon leader with the 1st Marine Division. Many Vietnam veterans have experienced anxiety and other effects of post-traumatic stress disorder (PTSD), both on the battlefield and upon returning home. Most soldiers who were involved in active combat situations in the war returned home with little assistance to make the transition back to civilian life. This segment from Iowa Public Television's Iowans Remember Vietnam documentary includes archival footage and a first-person account from a veteran of the war.
