A photo from the U.S. Air Forces in Europe historian's office shows some of the damage from a massive car bomb that exploded Aug. 31, 1981, in the parking lot outside the USAFE headquarters building on Ramstein Air Base, Germany. Twelve U.S. military members and two German civilians were injured. The German terrorist group, the Red Army Faction, later claimed responsibility for the attack. The incident prompted much stricter security measures, including pop-up barriers and a permanent security ring around the headquarters, according to information from USAFE. (Courtesy of USAFE)
