Cold War Files: All Units: Events: Operation Ranchhand Begins

Operation Ranchhand begins. The goal of Ranchhand is to clear vegetation alongside highways, making it more difficult for the Vietcong to conceal themselves for ambushes. As the war continues, the scope of Ranchhand increases. Vast tracts of forest are sprayed with "Agent Orange," an herbicide containing the deadly chemical Dioxin. Guerrilla trails and base areas are exposed, and crops that might feed Vietcong units are destroyed.
