The 86th Infantry Brigade Combat Team (Mountain) ("The Vermont Brigade") is an Army National Guard light infantry brigade headquartered in Vermont and subordinate to the 42nd Infantry Division. It was reorganized from an armored brigade into a light infantry brigade as part of the United States Army's transformation for the 21st century. The 86th IBCT utilizes the Army's Mountain Warfare school, co-located at Ethan Allen Firing Range in Jericho, Vermont, to train in individual military mountaineering skills. This is a capability the army had lost after the 10th Mountain Division inactivated after World War II, except for 3rd Battalion 172nd Infantry Regiment, which has its subordinate units split between Vermont, New Hampshire, and Maine.
