What feature enhances the mobility of the Avenger system?

The mobility of the Avenger system is primarily enhanced by its wheeled chassis design. This feature allows it to travel quickly and efficiently across a variety of terrains, providing greater operational versatility. The wheeled chassis enables the system to maneuver like a conventional vehicle, making it capable of rapid repositioning to engage targets or take cover when necessary.

In contrast, advanced armor protection, while crucial for survivability, does not directly contribute to mobility; instead, it may even add weight that can inhibit movement. Vertical launch capability is important for the effective launching of missiles but doesn't influence the system's mobility dynamics. Stealth technology is designed to reduce detectability by radar and other sensors, which enhances survivability but does not enhance the physical movement of the system. Thus, the wheeled chassis stands out as the key feature that significantly boosts the overall mobility of the Avenger system.
