Perform 5 dog tag kills in Multiplayer
You perform Dog tag kills by knifing enemies with the () while behind an enemy. If an enemy tries to knife you but you manage to counter them, this will also count as you still get their dog tags. You can also go for frontal knife kills but this normally takes 3-4 stabs and is not recommended as the enemy will almost always counter your attack. You can accumulate some fast knife kills on Domination or Team Deathmatch where you’re likely see several enemies in a small area.
