EDIT: WTF WHY ARENT THE PICTURES SHOWING UP
i unlocked some cool emblems today, i'll explain how i got them as well
hurt the enemy with my primary weapon then killed him off with my pistol - one shot with the RPD, then switched to magnum and shot him again (at close range)
shot an enemy and he went into last stand, then i killed him by throwing a STUN grenade directly at him (the impact killed him)
shot an enemy and he went into last stand, then i killed him by throwing a FLASH grenade directly at him (the impact killed him)
this is my favourite one and the one i'm using now
shot an enemy and he went into last stand, then i killed him by throwing a FRAG grenade directly at him (the impact killed him)
i think we should all play as a siccness clan and use this one as our emblem lol
i'm pretty sure i got this by killing someone with a throwing knife while i was blinded by a stun/flash grenade
