When moving an artillery piece, does it face the direction of travel when it is "un packed" from the transport.

Does it also come to be placed at the final waypoint of the vehicle it was being moved "in"

you can set bearing of "moved" artillery and all other ground units after you click finalize mission....
it will be placed on the spot where your last waypoint was and in the direction you chose - but be aware artillery will not have the ability to shot in the mission in which it was moved, it will be a truck
