Retired Col. Carrol C. Barrick, 73, who had 36 years of military service, most of it with the Army Medical Service Corps, died of cancer Aug. 15 at Potomac Valley Nursing Home in Rockville, where he had lived for about six weeks.

His last assignment before his retirement in 1959 was that of commanding officer of the U.S. Army Medical Depot in Vitry le Francois, France. He then returned to live in the Washington area.

Col. Barrick was born in Donald, Wash. He joined the Army in 1923, was promoted through the enlisted ranks and commissioned 10 years later into what became the medical service corps.

He was assigned to Walter Reed Hospital in Washington from 1934 to 1937. Other assignments before World War II, included Alaska and the Philippines.

In the early part of World War II, Col. Barrick served with the Army Service Forces at the Pentagon, where he helped plan the supply of medicines, hospitals and other equipment for the Mediterranean theater during the American invasion of North Africa.

Later in the war, he saw service in three major European campaigns. After the war, he was assigned to the Army General Staff here.

Col. Barrick went to 8th Army headquarters in Japan and then was moved to South Korea when the conflict broke out in that country. After duty in San Francisco, he was in the Office of the Army Surgeon General here from 1954 to 1957.

He is survived by his wife, Sharlette, of the home in Bethesda; a son, Bruce C., of Olympia, Wash.; a sister, Flora Abbot, and a half-brother, Charles Newton, both of Washington state, and a grandson.

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