The folding roof hatch on this M1064 is open and the 120mm mortar is deployed; the external fuel tanks are fitted on the vehicle rear as well. The hatch folds open, with one section opening to the left and two sections folding to the right. The tracks on this example are the single-pin T130E1. The .50cal machine gun is not fitted, but the mount is visible behind the driver's head. (Picture courtesy Armor Foto.)
