Austria became Vermont's third state partner on Oct. 15, 2021, making Vermont the fifth National Guard with three state partners. The countries' military cooperation stretches back to 1983, with partnerships between the Army Mountain Warfare School, U.S. Army Biathlon Program, and 86th Infantry Brigade Combat Team (Mountain) and their Austrian counterparts. The Vermont National Guard has also undertaken trilateral events with both Senegal and Austria since 2015 through the Physical Security and Stockpile Management Program, focused on safe munitions storage and disposal of expired munitions.
