In order to get the Clean Sweep emblem, you have to "Destroy 1 Tac Inserts in a single game".
I have EMP'd, shot, and held x over them. I have taken out at least 15 tac inserts already, and yet I still haven't gotten the challenge, nor the emblem.
Am I the only one with this issue? Is it a typo and you have to destroy multiples in one game?
