A M104 Wolverine

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 also features an advanced communications package designed to keep it in contact with local field commanders. However, the vehicle itself is completely unarmed.
