Agent Orange Overview: Approximately 20 million gallons of herbicides were used in Vietnam between 1962
and 1971 to remove unwanted plant life and leaves which otherwise provided cover for enemy forces during
the Vietnam Conflict. Shortly following their military service in Vietnam, some veterans reported a
variety of health problems and concerns which some of them attributed to exposure to Agent Orange or
other herbicides. The Department of Veterans Affairs has developed a comprehensive program to respond
to these medical problems and concerns. The principal elements of this program include quality
healthcare services, disability compensation for veterans with service-connected illnesses, scientific
research and outreach and education.
