Lieutenant General Louis Watson Truman (June 20, 1908 – December 2, 2004) was a senior United States Army officer.

The 2nd Armored Division at the time was commanded by one of the army's fastest rising officers: Brigadier General George S. Patton, Jr.

In March 1942, Truman was promoted to major and was assigned to United States Army Ground Forces headquarters, first as an assistant G-3 (operations and training officer) and later as secretary of the general staff for commander Lieutenant General Lesley J. McNair.

In early November 1944, now a colonel with only twelve years commissioned service, Truman landed over Omaha Beach with the 84th Division.

He saw combat in the European Theater along the Siegfried Line, the Battle of the Bulge, and in Germany from the Roer to the Elbe Rivers.

Truman received a promotion to major general in 1956, and with it the chairmanship of the Military Assistance Advisory Group, Karachi, Pakistan.

Truman later returned to the United States to take command of the 4th Infantry Division at Fort Lewis, Washington, from 1958 until 1960.

In 1962, President John F. Kennedy nominated Truman for promotion to lieutenant general and, from 1963 until 1965, he commanded the VII Corps at Kelley Barracks, Stuttgart, Germany.

Recently, Truman was honored by the West Point Society of Atlanta with its "Distinguished Graduate Award."
