During yesterday's clan operations for TDM I saw about 2 dozen people with those emblems. I was kinda pissed they didnt properly release them.
edit: word is that if your clan reached one of those levels yesterday then they unlocked the emblem. But the emblems that high ranking clans should have earned already are still locked for them. So after they patch it you'll receive all the ones you were supposed to.
edit II: I can confirm that, I just reached 27 from that clan op last night and now have the corresponding emblem. Too bad its one of the terrible ones
