These are from the initial production batch that 3/2 bde was given to certify and work out some kinks. You can barely see the MILES belts on the front vehicle (more evident by checking out the front cheeks - you can see the metal plates and wire w/ white tape). Note the DVE is in the first position. If we could see the sides of the vehicles the initial narrow, solid strut guard would probably be evident too. 3/2 also took these vehicles to Korea. Afterwards they got full production vehicles and then were deployed to Iraq w/ the DVE in the current, central front hull position and upgraded perforated strut guards, and slat armor.
