I cannot manually move the elevation trajectory up and down on any of the new artillery vehicles. The only way I can move this is with the Arty computer. This means I cannot put the cannon/rocket pod back down after I use it forcing me to drive with it in the air.
No one I have spoke to can figrue out how to manually change it. Moving the mouse up and down only moves the camera of the optics. when in thrid person mode nothing moves at all and you are stuck looking down the barrel.
If I have missed something then I am sorry for wasting your time.
