172nd Cavalry Regiment

The 172nd Cavalry Regiment is an armored cavalry regiment of the Vermont Army National Guard, with one battalion currently active. First organized in 1861, the regiment has seen combat in the American Civil War, World War I, World War II, and the war on terror. Originally an infantry regiment, elements of the unit were consolidated with an antiaircraft unit in 1959 and converted into an armored regiment. In 1964, the remainder of the 172nd Infantry was consolidated with the 172nd Armor, as an armored regiment.

In 2007, the regiment was retitled cavalry. In 1982, a new infantry unit designated the 172nd Infantry Regiment was organized in the Vermont Army National Guard, but it does not share the lineage of the previous 172nd Infantry/Cavalry, only the numerical designation.
