COAST ARTILLERY BATTERY training in Hawaii. Man at left is placing a round in the manual fuze setter of a 3-inch antiaircraft gun M1917M2. A plan for the defense of the Hawaiian Islands had been set up and joint maneuvers (land, air, and naval forces) were held periodically to test the various security measures.

BROWNING ANTIAIRCRAFT MACHINE GUN on a runway at Wheeler Field, Oahu, in the Hawaiian Islands. Early in December 1941 all the U.S. troops, including antiaircraft batteries, were returned to their stations from field maneuvers to await the signal for riot duty. Trouble was expected, and while Japanese diplomats in Washington talked peace, their Pearl Harbor Striking Force was moving eastward toward Hawaii. During this movement the fleet maintained radio silence and was not detected as it approached the islands. (.50-caliber antiaircraft machine gun, water-cooled, flexible.)
