By far the stupidest assignment out of any Battlefield game. Most LMGs don't have enough rounds unless you're 100% accurate, which is impossible without cheating, and they have that freaking cooldown mechanic even though they have reverse spread so you're SUPPOSED to fire them for extended periods, so you pretty much give a decent pilot enough time to escape anyway.
I've been trying for days and have only managed one, which was a fluke because a pilot bailed and the plane landed in front of me. If we didn't have that cooldown mechanic, or we had some kind of armor piercing bullet gadget, like the K bullet, but maybe less strong and like 30 rounds. As it is my accuracy is just plummeting and I have NOTHING to show for it. GG DICE.
