5th Infantry Division (Mech)

The 5th Infantry Division (Mechanized), known as the "Red Diamond" Division, was first activated in 1917 and served with distinction in World War I, participating in major campaigns in France. Reactivated during World War II, the division played a crucial role in the Normandy breakout, the liberation of France, and the crossing of the Rhine into Germany. During the Vietnam War, the 5th Infantry Division (Mech) was deployed to South Vietnam from 1968 to 1971, conducting operations primarily in the Quảng Trị Province. Throughout its history, the division was renowned for its adaptability, fighting both as a conventional infantry and later as a mechanized force, before its inactivation in 1992.
