10th Mountain Division

The U.S. Army's 10th Mountain Division is currently a light infantry division; the name is historical, remembering a Second World War formation explicitly trained and equipped for mountain warfare. It is, however, unusual in being the division, or constituent light brigade combat teams that can deploy with the least amount of aircraft or ship transport.

Due to the ease of deploying it, it has been chosen for peacekeeping operations, or for rough terrain, as in Afghanistan, where armored and air assault divisions could not easily operate.
