The principal banner of the thirty-seventh Special Operations Association Reunion, Las Vegas, 2013, sponsored by Budweiser. At its right is the association's shield: a skull in a green beret on a red and yellow field, adapted from the recognition insignia of MACV-SOG, the Studies and Observations Group that conducted classified cross-border reconnaissance during the Vietnam War. Easels and velvet ropes stand ready for a display exhibit still being set up. Project: 219854
