The 1st Cavalry Division, often known as "1st Cav," is a renowned unit of the United States Army established in 1921. Originally organized as a horse-mounted cavalry division, it transitioned to an armored and air-mobile force, famously spearheading the use of helicopters in combat during the Vietnam War. The division played pivotal roles in major conflicts, including World War II in the Pacific, the Korean War, Vietnam, Operation Desert Storm, and the Global War on Terror. Today, the 1st Cavalry Division remains a key heavy armored division based at Fort Cavazos (formerly Fort Hood), Texas, continuing its legacy of adaptability and combat excellence.
