The armor was not a passive system. Upon activation it conferred improved durability and immunity to EMP at the expense of a vehicle's rate of fire. This could be advantageous or disadvantageous depending on the situation.
Adaptive armor may be used in conjunction with the Railgun Accelerator. The accelerator almost restores the rate of fire to normal, while the armor partially mitigates the damage inflicted on the vehicle by the accelerator. The Adaptive armor was also useful for allowing a particular unit, such as the Mammoth, to take all the abuse for the other units with the adaptive armor actived, while the other units have the Railgun Accelerator active. Adaptive armor was also useful if units had to pull out of a hot spot, as it allowed them better survival chances.
