In 1962, the United States Military began to use a potentially toxic chemical known as Agent Orange. The toxic chemical was used a defoliant to destroy crops and eliminate ground cover during the Vietnam War. Vietnamese troops would hide underneath the thick forest and make it impossible for United States troops to spot them. So in 1962 the Army began using Agent Orange as a way of eliminating that problem. The government had very little knowledge about the deadly chemical but went ahead and used it anyway. They had no idea of the disastrous long-term effects that it would have on men, women and children. But the hardest group hit by the chemical was not Vietnamese civilians but United States troops. In 1962, Project Ranch Hand was being deployed all over Vietnam. The idea was to destroy the forest on the battle field and make it easier for the United States troops to see the Vietnamese soldiers. The term "agent orange" was given to the chemical because of the bright orange canisters that it was stored in. (Online, Mar 27. 1999) The orange canisters were used to distinguish the chemicals in the warehouses so that they would not be confused with anything else. During the Vietnam War, 11.2 million gallons of Agent Orange were used as defoliants throughout Vietnam and Southeast Asia. (Online, lewispublishing, Mar 27. 1999) Approximately 2.6 million United States soldiers served in South Vietnam and nearby areas during the war. (Online, lewispublishing, Mar 27. 1999) As the planes would drop the massive amounts of Agent Orange onto Vietnam, United States soldiers would unknowingly walk to certain disaster. The deadly chemical affected everyone from ground troops to pilots to seamen. The hardest hit of course were the ground troops. In some cases the defoliant was dropped almost right on top of them while in the field. At that time they may have had some idea that it might be potentially hazardous but they were not certain.
