The First Infantry Division, known as the "Big Red One," is the oldest continuously serving division in the United States Army, activated in 1917 during World War I. The division distinguished itself in the trenches of France and later played a pivotal role in the D-Day landings at Omaha Beach during World War II. Throughout the Cold War, the division was stationed in Germany and participated in operations in Vietnam, the Gulf War, and the Balkans. In the 21st century, the Big Red One has served in both Iraq and Afghanistan, maintaining its reputation as a premier fighting force.
