The Kamu

No idea

I have played a lot of NQ where is FT icons and i never took closer look on them.

So it is whatever to me, i let others to deside whatkind of symbol they want.

But it must be clearly visible, good color might be something like red,orange,yellow.

I agree but not only in teamkill part.

It would be nice to get kills by pushing enemy players to dead.

Also when you throw nade and enemy fly up in the air and die by faling, Player who threw nade should get the kill, not nature

Me and few of my friends have noticed that there's no fireteam icons.

So fireteam icon above your head would be nice. Just somekind symbol above every member in your fireteam.

That makes easier to track down your fireteam members.
