Infantry anti air capabilities

I've been seeing a lot of frustration over the ineffectiveness of handheld anti air launchers in the game and i feel it too. A good pilot will simply play it safe and only take risks when flares are avalible.

I feel like a good compromise would be to allow *some* damage to seep through by near impacts, i've had rounds impact the flare really close to the aircraft and it would bring a lot of satisfaction back into the game if the missile atleast did 20-50% of the damage a direct hit would.
