M104 Wolverine

The M104 Wolverine Heavy Assault Bridge is an armored combat engineering vehicle designed to provide deployable bridge capability for units engaged in military operations.

Overview
For over a quarter of a century the US Army has made use of armored bridgelaying vehicles based on the M48 Patton/M60 series of tanks. In recent years, however, the Army discovered that the aging M60 AVLB (Armored Vehicle Launched Bridge) was too slow to keep up with the M1 Abrams during field maneuvers. Additionally, the Abrams was so heavy that it could safely cross the AVLB's bridge only at a very slow speed.

Because the Wolverine is essentially an M1A2 SEP tank with bridgelaying gear instead of a turret it shares virtually all of the parent vehicle's speed, mobility, survivability, and automotive components. This commonality was a key design factor in the Wolverine's development. The Wolverine is operated by two crewmen who sit within the hull. Both crewmen have access to the bridging controls, while the bridge itself is carried in two sections above the hull. Once a bridging site is chosen the vehicle securely anchors itself in place with a spade. The two sections of the bridge are joined together, and then the entire bridge is extended across the obstacle and dropped into place. During launch the crewmen have the ability to make minor corrections if needed. Once operations are complete the Wolverine drives across the bridge and retrieves it from the other side simply by reversing the process. The bridge can be launched in under 5 minutes or retrieved in less than 10, all without the crewmen ever leaving the safety of their vehicle.

In Call of Duty: Modern Warfare 2
The Wolverine is seen in the mission Team Player. It must be protected from enemy fire while it sets up its bridge on a broken overpass. Once completed, the player, while in a Humvee, moves across the bridge along with the rest of the Rangers.
