This is a later-production V-100, or an M706, as evidenced by features such as the engine compartment access hatch on the rear left side, the cover over the engine air intake grille on the vehicle roof, a single vision block and firing port in front of the two-part side door, and the circular wheel cutouts instead of the earlier angled cutouts. The turret had a single top hatch and vision blocks around its base.
The extension to the exhaust housing can be seen on the hull's left rear corner, and the rear door can be glimpsed on the opposite side of the vehicle. A towing pintle is mounted between the rear wheels.
The rear door with its vision block and firing port is better shown better in this image. This door is also two-part, with the upper and lower halves both opening outward. The vision block and firing port in the right rear corner can also be seen. The turret hatch is missing from this vehicle.
The offset placement of the turret armament can be seen here. The front vision blocks and firing ports in the front and forward sides are also shown.
The location of the vehicle's winch can be discerned here, with the fairleads in the lower front hull and access hatch in the upper front slope. The front armor continues down between the wheels to help prevent the front differential from fouling on obstacles. The raised contour of the front roof hatches can also be seen in this picture.
This vehicle's winch has a line ready for deployment, and the front roof hatches are open. The turret periscope guard can be seen on its roof, but the machine gun mount is missing.
Details of the installation of the front leaf springs can be seen here.
The turret of the normal M706 was removed in favor of an armored parapet in this version of the vehicle. The opening in the roof was covered by folding doors, and machine guns could be mounted around the parapet as shown. Note the operation of the open side door and interior details of the vision block and firing port. (Picture taken 15 July 1977 by SSGT Mike Creen; available from the National Archives.)
Another view of the XM706E2 (and a view of some poor trigger discipline) is provided here. These men were participating in Exercise Team Spirit '81. (Picture taken 1 Mar 1981 by MSGT Bert Mau; available from the National Archives.)
The driver of the V-150 was provided with a second vision block, and the front firing port was deleted. Note how the driver's vision blocks are angled outward from the hull in contrast to the earlier design. This vehicle is crewed by a Botswani task force searching for weapons during Operation Restore Hope. (Picture taken 25 January 1993 by PH1 R.J. Oriez; available from the National Archives.)
