The Wrecker Unit was designed as a heavy hitting close range unit with a major role in battlefield salvage

In robot mode, the Unit's main features are it's large Pulverizer Arm and it's Hammer Hook Arm. It's specialized optic configuration allows it to scan the area for usable materials and target weak points. It's hook arm can be used for grappling, but due to the Unit's weight, it is not safe to do repeatedly. Doing this however allows it to do "ground slam" attacks to trip up enemies.
In hooked truck mode, it's hook is excellent at removing salvage and even the wounded from the battlefield. It's lack of speed is made up by it's strong armor, allowing it to give cover. It is also capable of doing heavy ramming attacks to disorientate enemies.
