Another thing that seems to be overlooked is who controls ( called ) a arty mission when you click a FOO ( or command unit ) the ones that FOO ( or command unit ) called show in green
and
so when you pick a FOO and go to the bombardment menu it will show which one that FOO is responsible for and if you don't like his LOS simply pick a FOO that has better LOS and adjust the fire and then THAT new FOO is the controller
The "problem" is....the game only tells you who is controlling it when you enter the bombard menu and then it's whatever command unit you selected so he's the controller if you adjust fire but there is no way to know which of the FOO's you might have on map are the ones controlling a fire mission NOW
I see your point but I see Andy's as well....if you have a fire mission and you have a FOO in a better position to observe it select him and then make an adjustment and then that FOO is your controller...if you don't make an adjustment then it's the original observer who still controls it but the missing info is who that is.....Andy's POV is it does not matter who controls it before you adjust fire only that you did adjust fire with the observer in the best position and now he's the controller for that battery fire mission
