I can't say it's not the 10th, I'm just adding something for consideration.
"The 3rd Battalion, 172nd Infantry Regiment (Mountain), also known as the "Mountain Battalion", is a Vermont Army National Guard light infantry battalion which specializes in mountainous and cold weather operations. The unit falls under the command of the Vermont Army National Guard's 86th Infantry Brigade Combat Team (Mountain).
Before the creation of the 86th IBCT (MTN) in 2008, 3-172 IN (MTN) was recognized as the only conventional unit in the United States Army trained and equipped for mountain operations. 3-172 IN (MTN) draws strong heritage from the original 10th Mountain Division (Alpine) of World War II fame both in the type of training they conduct and in the specialized equipment the unit maintains."
