Retired Army Col. Charles F. Manov, 67, a decorated combat veteran of World War II who later worked as a computer programmer at the Pentagon, died of cardiac arrest Saturday at Walter Reed Army Hospital.

As an officer in the 7th Infantry Division, Col. Manov took part in the amphibious assault on Attu in the Aleutian Islands. He also participated in the division's landing at Leyte and Okinawa. He achieved the rank of major during the war.

His postwar duty included tours in Korea and West Germany. During the mid-1950s he was an American representative to Nato's planning board for inland surface transport and a transporation officer with Vii Corps.

From 1963 to 1964, Col. Manov served as chief of organization and training of the Army Transporation Corps. He was an ammunition control officer at Oakland Army Base in California before retiring from active duty in 1967.

His decorations include the Legion of Merit, the Bronze Star with two oak leaf clusters, and the Purple Heart.

For the past 12 years, he had been a civilian computer programmer and micrographics analyst with the Department of the Army.

Col. Manov was born in San Francisco. He was a 1936 graduate of the University of California at Berkeley. An officer in the Army Reserve, he was called to active duty in 1940.

He is survived by his wife, Janet, of the home in Arlington; two daughters, Susan Ann Manov, of Alexandria, and Evelyn Sprinsky, of Canton, N.y.; a brother, Anthony R., of Pleasanton, Calif., and one grandchild.

The family suggests that expressions of sympathy be in the form of contributions to the American Heart Association. CAPTION: Picture, CHARLES F. MANOV
