This hastily constructed gun emplacement in front of Hangar 5, Hickam Air Field, was manned shortly after the raid Dec. 7, 1941 by Pvt. 1st Class Raymond Perry (left, with binoculars) and Cpl. Howard Marquardt of South Dakota. A burned-out aircraft engine, sand bags, table, and debris from the attack made up the construction material for this bunker. (Courtesy photo)
