Soldiers learn to assemble a Mabey Logistic Support Bridge from members of the Vermont Agency of Transportation as part of a simulated bridge collapse during the Vigilant Guard 2016 training exercise in Berlin, Vt., July 29, 2016. The soldiers are assigned to the Connecticut National Guard’s 250th Engineer Company. The National Guard and U.S. Northern Command sponsored the exercise, which provides an opportunity for service members to improve cooperation with civilian, military and federal partners as they prepare for emergencies and catastrophic events.
