Former Marine Air Traffic Controller, now Army. Can I wear Army Aviation Badge? Marine didn't, Army does!?

I am not sure what the requirements are exactly. I know the Army considers their flight physicals and knowledge in field worthy of the badge. Marines, however, were not awarded these badges as ATC. So since I am in the Army now do I qualify for this badge? I held the MOS at some point in my military career? I have looked but can not find any information on this. Thanks.
