in attack mode you can score perks for kills using the gun manned by pilot. haven't done it in a couple of years.
any other kills done by gunner position don't count.

I would very much like to test that when I see you online next time. You can shoot down my fighter from gunner position in a 'bomber' in attack mode, and we'll see what happens to perks. I'm very curious, never experienced such a thing.
However, even if that's a thing, it doesn't read to me anything like AKKuya said, so I also wish he would clarify his statement ("Only two ways to get bomber kills.") for me.
