4 . The mobile gun system according to claim 3 , comprising a sensor connected to the controller, wherein the controller is configured to determine whether the peak loading condition has passed based on information detected by the sensor.

5 . The mobile gun system according to claim 4 , wherein the sensor is configured to detect information indicative of the recoil mitigation force.

6 . The mobile gun system according to claim 5 , wherein the recoil mitigation system comprises a fluid configured such that a pressure of the fluid increases when the gun barrel moves relative to the chassis due to the recoil force, and wherein the sensor is configured to detect information indicative of a parameter of the fluid.

7 . The mobile gun system according to claim 6 , wherein said parameter is a pressure of the fluid.

8 . The mobile gun system according to claim 1 , wherein the braking system comprises an anti-lock braking system (ABS).

9 . The mobile gun system according to claim 1 , comprising a plurality of wheels and/or tracks, and wherein the braking system is configured to brake at least one of the wheels and/or tracks to retard said recoil movement of the chassis.

10 . The mobile gun system according to claim 9 , wherein the controller is configured to adjust the amount of braking applied to one or more of the wheels and/or tracks to adjust the direction of recoil movement of the chassis due to the recoil force.

11 . The mobile gun system according to claim 10 , comprising an orientation sensor configured to detect information indicative of the orientation of the chassis, wherein the controller is configured to adjust the direction of recoil movement of the chassis based on the information detected by the orientation sensor.
