Possible damage hack with the MAA, here is the video for proof:

Would be great if we could get some spectator footage or more of these kind of clips. It does in fact look like he onetapped that chopper from 91 health down to 0 however one frame before the actual killcam poped up the screen said "Killed in Action". Maybe something rammed you prior to that or your gunner triggerd a tv bug while the MAA was shooting at you thus getting the kill with basically no effort.

Don't think those few seconds are enough but i'll keep my eye on him!
