U.S. troops search villages in the Bong Son Plain area for Viet Cong and sympathizers who may remain following a two-day battle. The Communist stronghold threatens all allied supply routes. American troops exit a military transport helicopter in the jungle. Troops begin searching a village. A soldier places a listening device against a wall. A soldier searches a debris pile for hidden villagers. An elderly Vietnams man comes out from a hidden bunker. Villagers are gathered together for processing, and then march out of the camp with the soldiers. Many of the women carry small infants. VERY GOOD FOOTAGE.
