While fighting in the war in Vietnam, American soldiers often had trouble finding attackers in the dense jungles.

The Vietnam War was fought from 1 November 1955 to 30 April 1975 and it ended up with the victory of the North Vietnamese and the National Liberation Front. The involvement of the United States in the war was direct; however, most soldiers in Vietnam were not used to fight in dense jungles, which were also infested with mosquitos that carried Malaria. Moreover, during the war, soldiers from Vietnam used to hide behind the trees in the dense jungle for camuflage in order to carry out effective attacks against the American soldiers.
