The vertical rear side armor is illustrated on this vehicle, and the machine gun mount and skate rail can be seen ringing the commander's cupola. Latches and bump stops for the outward-folding roof hatches line the top of the rear of the vehicle, and the mounting point for the secondary mortar baseplate can be seen at the extreme rear of the side. This crew belongs to 1st Squadron, 2nd Cavalry Regiment, and was taking part in Operation Atlantic Resolve in Lithuania.

The roof hatches are open on this vehicle, and the 120mm mortar is deployed. The right side roof hatch of the passenger compartment must be closed before and opened after the left to provide a seal for the interior.

The 120mm mortar system, the muzzle of which is under a canvas cover, can be seen in this vehicle. Seats for the gunner and assistant gunner are mounted on either side of the rear ramp, and can be folded out of the way or for use as platforms, as shown here. The soldier facing the camera is assistant gunner PFC Kyle Blignaut of Company B, 1st Battalion, 17th Infantry Regiment, 2-2 Stryker Brigade Combat Team, 7th Infantry Division.

The ammunition stowage in the left rear of the passenger compartment, composed of six vertical and six horizontal racks, is for 120mm ammunition. Up to 48 mortar bombs can be stowed in this rack, and the vertical stowage allows for proper orientation of white phosphorus rounds. Another ammunition rack is opposite the 120mm rack, and this can be used to stow 60mm, 81mm, or 120mm rounds. In this image, PFC Tyler Quick is hanging a 120mm round during Operation Atlantic Resolve in Rukla, Lithuania.

Details of the mortar mount and the vertical 120mm stowage can be seen in this image. The screen on the mortar mount is the gunner's display, which shows elevation and deflection orders and gives the gunner the ability to check fire. Here, SPC Jeffery Holcomb from HHC, 2nd Battalion, 23rd Infantry Regiment, 4th Stryker Brigade Combat Team, 2nd Infantry Division sits on the ammunition bearer's seat and is monitoring the radio at Forward Operating Base Falcon.

The secondary mortar baseplate is stowed on the rear of the side of this vehicle, and a ventilation fan can be seen on the right-hand roof hatch. Note the lip on this hatch, which was designed to go under that of the left-hand roof hatch. The conical blast attenuator device on the mortar's muzzle can be removed when the mortar is stowed. This crew belongs to the 1st Battalion, 27th Infantry Regiment, 2nd Stryker Brigade Combat Team, 25th Infantry Division, and is firing at the Rodriguez Live Fire Complex near the DMZ in South Korea during Exercise Foal Eagle 2015.
