Battletech mechs in combat on a dusty planet HD Wallpaper

Three mechs are engaged in battle on a desolate, dusty planet. The lead mech is a large, blue and grey bipedal robot firing lasers. To its left, a larger, darker mech also fires lasers. To the right, a smaller, quadrupedal mech fires missiles. The sky is hazy with two moons visible and several small aircraft in the distance.
