The Vietcong made sure they picked battles they would be able to win. Weapons included daggers and swords, and explosives captured from the Americans to ambush patrols. Booby traps were made from pointed bamboo sticks, mines, grenades and artillery shells. The Vietcong wore no uniform and could not be found in any particular location. Tunnels existed for them to escape into the jungle. The cells they worked in were very small so that if captured, they could not be tortured for information about others.
