Fireteam 2x melee bindings?

#1

Hi.
I recently started playing and noticed that the Fireteam have 2 key bindings for their melee attack, how come?

2 different types of knife attack.

Ok, thanks!

Actually, it seems as if it’s still one type of attack, when you bind one the other one also gets bound on that new button.
Maybe it’s a miss from the game developers.
