DEFENSE DEPT. PHOTO (MARINE CORPS) A4503022. May 8 1965, Sgt R.O. Shaw.
Caption: Locating a Sniper—A rifle squad from Company “D,” 1st Battalion, 8th Marines, 4th Marine Expeditionary Brigade, searches for a sniper firing at the position inside the International Safety Zone in Santo Domingo. Note the M1 helmets, Korean War style flak vests and M-14.
