A panelist speaks during a symposium session at the 38th Special Operations Association Reunion, Las Vegas, 22 October 2014. His navy ballcap reads 'AIR FORCE' above 'RETIRED', one of the commonest forms of veteran identification worn at such gatherings. Aviation devices on the other panelists' shirts — an aircraft silhouette, an embroidered eagle — indicate a session concerned with air support for MACV-SOG cross-border operations. Sessions like this are the principal mechanism by which reunion attendees record and pass on their operational history. Project: 219867
