172nd Infantry Regiment (United States, 1982-present)

The 172nd Infantry Regiment is a Vermont Army National Guard infantry regiment which specializes in mountainous and cold weather operations. It falls under the command of the Vermont Army National Guard's 86th Infantry Brigade Combat Team (Mountain). Before the creation of the Infantry Brigade Combat Team in 2008, the regiment was recognized as the only conventional unit in the United States Army trained and equipped for mountain operations. The regiment draws heritage from the original 10th Mountain Division, which fought during World War II, both in the type of training they conduct and in the specialized equipment the unit maintains.

The regiment shares a name and numerical designation with the former 172nd Infantry Regiment, which is now an armored cavalry unit, but the two units are not lineally related.
