Challenge not completing

Ive been sitting here for 6 **bleep**ing hours trying to do damage to painted targets. 1. Recons dont even know they can paint targets. 2 infinite flares on jets and helicopters need removed. 3 aa missles need infinite lock on range and ignore flares when tracking a painted target. 4 my misslise should never miss for no reason. 5 why the **bleep** when i actually get a hit on a painted target does it not count. One of you devs need to go into my account and mark the challenge as completed
