Yeah, it actually happened to me. I tried to do Heavy Attack and got 2 Light Attacks as a counter then tried to kick and got Heavy Attack and died iirc. I was pretty bad there and it's not so common to be killed by a knife to me. So it was my mistake. And I never think a knife could hit that hard because I was also carrying MoN iirc. But what are you even talking about? If I'm Tac I shouldn't go for melee or what? Because yes as Combat Knife user you wouldn't have a chance. At least high chance. They can lock-on you know? Ah yeah sometimes it works to use them living cover against their team.
