I dont know how to get that percise one... I know i have it but i dont know how i got it. But to get a bunch of Emblems and Titles just go to barracks and go to Payback or different things and if you complete them you will get a bunch of neat stuff.
Plant two bombs in hardcore search and destroy.
You have to kill 200 enemies flashed by you flash grenade the challenge is in the presteige section
Its probably a later emblem for dlc
You unlock Claymore at Level 53 in MW3! :-)
Nothing they are the first emblem you unlock.
the colour of prestige 3 in mw3 is blue
Kill 2 or more enemies with a single AT4 or RPG, 50 times
you have to win 30 search and destroy games
Maybe there is something wrong with ur system, when it is supposed to unlock an emblem, does it come up with a error message etc. If so, get help. If not, then just level up, kill stuff etc. If u only play MW3 single player, then u cant unlock any emblems there. Same with spec ops I think. Source: Got the game
find the custom class and unlock them
Holt theres a emblem like that? look on Google
