*AHEM* We are happy to provide air support, but it's very simple... when you ask for it, you must give us the coordinates of the enemy, not the coordinates where you are.
If this is the case, then god help us that procedures are so out of sync. What chance for safety is there if one side gives its own co-ordinates on the basis that this communicates the position that shouldn't be attacked while the other understands this to be the position that should be attacked?
Hopefully there is a more acceptable reason.
