Agent Orange Definition - What is Agent Orange?

Agent Orange is the American military term for the defoliant sprayed across Southeast Asia during the Vietnam War to destroy crops.
The U.S. program of defoliation, codenamed Operation Ranch Hand, sprayed more than 19 million gallons of herbicides over 4.5 million acres of land in Vietnam from 1961 to 1972.
The effects of Agent Orange, which contain the highly toxic substance dioxin, are only now being understood.
Some veterans have developed cancer or skin conditions as a result of contact with dioxin; others, exposed to this chemical, have had children born with birth defects.
The effects of “Agent Orange” were and still are devastating for the Vietnamese population.
