The map needs to highlight where a Commander has thrown any coloured smoke for Fire Support requests.
Too many idiot commanders are throwing Gunship smoke ON a defend objective and getting their team mates killed!
If the map indicates is then players can move out of the way of their moronic commanders actions.
Observers should be able to deny commander requests. Commanders haven't earned the rank to make orders on their own, they just picked the class. An observer should have the right to refuse dumb Fire Support requests.
