The strider commander turret has no stabilization at all and when the vehicle is tilted, the view remains level while the controls behave relative to the vehicle (see screenshots).
Turning the view horizontally leads to the camera performing a transversal or diagonal movement. This is counter intuitive and further increases the difficulty of keeping a (moving) target in view, even when the vehicle has stopped.
The commander turret of the Strider needs to be stabilized and the view should reflect the proper orientation of the vehicle.
Compare the screenshots below: image 1 one shows the Strider standing on a slope, tilted a few degrees to one side. But when looking through the commander optics, the view is perfectly level (image 2).
Images 3 and 4 show a similar scenario.
