Broken/Stupid Challenge Tracking

Engineer Expert 2 - Destroying aircraft only counts when the pilot stays in. They can bail, and you don't get it even if the helicopter gets destroyed on the way down. 

Support Specialist 3 - Incendiary damage only counts on a direct hit. This is ridiculous because the point is to airburst the WP down onto people. 

Recon Specialist 1 - What counts as spotting enemies on OBJ with recon devices, because I have used the crap out of the drone and don't get any. The TUGs don't seem to do it, and the prox grenande has such a small radius. Also, 300, seriously? What counts?

Conquest Challenge 4 - Own all points when the game ends. WTH. Let me just lock an item behind the abilities of 63 other people. 

Headshot Expert 3 - Three headshot kills with sidearms without reloading? The magnum doesn't have a one-shot headshot, and all the other pistols have **bleep** damage. I routinely hit people with 5-6 shots and get turned on. 

Also, I didn't buy BF6 to play the FREE Redsec. Stop giving me BR/Guantlet Challenges. If you have to, give us more than five rerolls.
