Guy S. Howard, 51, a retired Army first sergeant who served in the Korean conflict and Vietnam and who suffered eight wounds during his military career, died Monday at the Andrews Air Force Base Hospital following a heart attack.

Mr. Howard, who settled in the Washington area after his military retirement in 1969, was born in Madison, Maine. He enlisted in the Army in 1948 and was assigned to a mapping unit in the Far East. He fought in the Korean conflict and was wounded several times.

Later assignments included various military posts in the United States, a tour in the office of the U.S. military attache in Beirut, Lebanon, from 1954 to 1959, and in the office of the military attache in Belgrade, Yugoslavia, from 1960 to 1965.

He then went to Vietnam, where he served with Special Forces units and received other wounds. He retired from Fort Holabird, Md.

For his wounds, Mr. Howard received the Purple Heart medal with seven oak leaf clusters. He also held the Silver Star, the Soldier's Medal and the Bronze Star with an oak leaf cluster.

Mr. Howard settled in Bladensburg after leaving the Army and for the next two years was a vice president for Overseas Services, a firm that recruited civilians for work with U.S. firms overseas. He worked briefly as a vice president of commercial sales for Trans Global Overseas Network. He then resumed college studies he had begun in the service and completed the course requirements for a degree in acccounting at the University of Maryland. He lived in Bowie for the past three years.

He was a member of the Disabled American Veterans and of Elks Lodge No. 2266 in Glen Burnie.

His marriage to the former Ella Jensen ended in divorce.

Survivors include his wife, Nora, and their son, Guy, of Bowie; two sons by his first marriage, Lance and Kevin Howard, of Tucson, Ariz.; one brother, Harold, of Westboro, Mass., and one sister, Madelene Colter of Springfield.

The family suggests that expressions of sympathy be in the form of contributions to local chapters of the American Heart Association, or to the American Cancer Society.
