Vendor and display tables in a hotel ballroom during the 2013 Special Operations Association Reunion. Alongside rosters, photo albums and loose prints, exhibitors mounted period photographs on display boards and hung a military flight jacket for viewing, while a flat-panel monitor cycled through images of Southeast Asia-era aircraft. Annual reunions such as this one - long associated with veterans of the Vietnam-era Studies and Observations Group (MACV-SOG) - serve as informal archives where members share photographs, identify comrades and preserve unit history.
