The Tenth Mountain Division is a light infantry division of the United States Army, originally formed during World War II. Established in 1943, it was designed for mountain warfare and trained in the Rocky Mountains of Colorado. The division played a significant role in the Italian Campaign, where its soldiers were known for their skiing and climbing skills. After World War II, the Tenth Mountain Division was inactivated but later reactivated in the 1980s. Today, it continues to serve as a key component of the U.S. Army, specializing in rapid deployment and operations in challenging terrains, including mountainous regions.
