Retired Army Maj. Gen. Douglas V. Johnson, 76, whose last assignment was director of strategic plans in the office of the Joint Chiefs of Staff, died Sunday at this home in Alexandria.

He had retired in 1960 after two years in that assignment. During that period, he also had lectured at the National War College, the Army War College and the Air War College.

Born in Danville, Va., Gen. Johnson was commissioned in the field artillery after graduating from Virginia Military Institute in 1922. Prior to World War II, he served at various posts in this country and in the Philippines.

During the early part of the war, he was chief of the African-Middle East section in the operations and plans division at the Pentagon.

Gen. Johnson was sent to Europe in the early part of 1944 to serve as assistant commander for plans and operations of the 7th Army Corps. He landed with the corps in the Normandy invasion.

Later that year, he took command of the 223d Field Artillery in Hawaii in preparation for the invasion of Japan. At the end of the war, he commanded Army Ground Forces in Saipan.

In 1947, Gen. Johnson returned to Washington as the Army representative to the National Security Council and chief of the Army's Policy Branch.

In 1952, he became artillery commander of the 43d Infantry Division in Germany and then was deputy chief of staff of the U.S. Army Europe with headquarters in Heidelberg.

He was deputy chief umpire for Exercise Sagebrush, chief of staff, Third Army, in Louisiana before his final assignment here.

After retiring from the military, Gen. Johnson served as a civilian director of policy review for international security affairs in the office of the Secretary of Defense. Later he was a consultant to the Agency for International Development, retiring for a second time in 1966.

His many decorations included the Distinguished Service Medal the Legion of Merit and the Bronze Star.

He is survived by his wife, Helen Jeanne Johnson, of the home; a daughter, Jenane I.B. Hughes, of Concord, N.C.; a son, Army Maj. Douglas V. Johnson II, stationed at West Point, and four grandchildren.

The family suggests that expressions of sympathy may be in the form of contributions to the American Cancer Society.
