Two U.S. Air Force pilots pose beneath the "Home of the Spads" sign, the nickname for units flying the propeller-driven A-1 Skyraider ("Spad"). The signage identifies the 56th Special Operations Wing, Operating Location A, likely at Nakhon Phanom Royal Thai Air Base, a major staging point for Skyraider combat rescue and strike missions over Laos and North Vietnam during the Vietnam War.
