Engineer Specialist 2 Challenge

Yeah,

Shot 10+ Aircraft as engineer, Progress still shows 0/50....

Tengo el mismo problema he bajado a 5 helicopteros con la AA y nada

Not bugged, done it pretty easy. You have to have "ENEMY Vehicle Destroyed" or assist in Vehicle destruction to count, if ppls jump out before your rocket hit or you hit an empty vehicle it won't count toward progress. 

I have just had that come up 3 times from aircraft I've destroyed and it's not progressing for me.

13/50 but if i hit and after this idiots die in earth and i dont get assist, 1 time i shoot with rpg, get double kill with this heli i shoot and dont get assist, if u hit aircraft with minigun you dont get assist, sometimes i dont get progress for kill heli, sometimes my roket go throw enemy, this chellenge is impossible

Same issue - been hitting helis with the AAA rocket for the past hour and 0 progress 

This bug is very real and active. I got to progress 22/50 and now it simply stopped. I destroyed at least 10 vehicles after that and it is not increasing the kills at all

Your best bet is to use the AA gun that’s on the maps, personally I’ve found the AA turret on mirak valley that’s next to the big open field to be a solid option, though it’s not as fast as I’d hoped, but you’ll make progress, I find it a more viable and less stressful option than using the stinger, 

if anyone knows of better spots feel free to reply

edit: running combat engineer rather than anti armor and play and capture objetives until you get the “overheat control” ability makes things a bit easier on this method, hopefully this helps 

If you shoot an aircraft with a rocket and they crash into the ground/building after severe damage it doesn't count. That's a load of crap. It should count. I forced them to crash, why wouldn't that count as destroying them?

So then yes it is bugged. Just because they jump out last minute the game still knows they were in it so those should still count.
