1. A self-propelled gun system comprising:
a chassis extending along an x-axis, a first end of the chassis and a second end of the chassis spaced apart from one another along the x-axis, the chassis extending along a y-axis, a first side of the chassis and a second side of the chassis spaced apart from one another along the y-axis, the x-axis being at right angles to the y-axis;
a gun barrel having a gun barrel axis, the gun barrel being mounted to the chassis by a pivot mount, the gun barrel being pivotable relative to the x-axis about a pivot axis aligned and/or parallel with the y-axis;
a chassis suspension system comprising a wheel arm extending away from the chassis to a wheel, the wheel being rotatably mounted on the wheel arm, the wheel configured for engagement with, and travelling along, a support surface to support the chassis, when in transit, a distance (Dz) apart from the support surface in a z-axis, the z-axis being perpendicular to the x-axis and y-axis; and
a recoil mitigation system comprising a recoil support leg which extends away from the chassis to a foot end, the foot end operable to engage with the support surface during firing of a projectile from the gun barrel, the foot end operable to be spaced apart from the support surface when the gun system is in transit, the recoil support leg configured to react against recoil force (Fr) in the z-axis from the firing of a projectile from the gun barrel, the recoil mitigation system further comprising a wheel brake control device configured for applying a braking force to the wheel after the firing of a projectile from the gun barrel and after the wheel has started rotating along the support surface in response to the firing of a projectile from the gun barrel.
