The 915A5s of the 131st Transportation Company, a unit of the Pennsylvania Army National Guard, drive past a Canadian Reserve sign on their route to Lieutenant-Colonel George T. Denison III Armoury to pick up Canadian military vehicles as part of the mission STEADFAST WARRIOR, on August 12, 2012. Just like the Canadian Reserve sign displays, the U.S. Army National Guard employs both part-time and full-time soldiers.
