Which of the following was a tactic used by the us during the vietnam war? spreading agent orange disguising troops as the enemy fighting guerrilla warfare disguising troops as civilians

The answer is option 1: Spreading Agent Orange.

As the war was developing, the U.S. initiated the Operation Ranch Hand (1961-1971), an aggressive program of chemical warfare, where millions of gallons of various powerful and highly toxic herbicides were spread over Vietnam to destroy forests that covered the enemy. The Agent Orange was the herbicide more used. It was later proven that it caused major health problems for the individuals who were exposed.
