Agent Orange was a blend of tactical herbicides the U.S. military sprayed from 1962 to 1971 during the Vietnam War to remove the leaves of trees and other dense tropical foliage that provided enemy cover. The U.S. Department of Defense developed tactical herbicides specifically to be used in “combat operations.” They were not commercial grade herbicides purchased from chemical companies and sent to Vietnam.
More than 19 million gallons of various “rainbow” herbicide combinations were sprayed, but Agent Orange was the combination the U.S. military used most often. The name “Agent Orange” came from the orange identifying stripe used on the 55-gallon drums in which it was stored.
