Forum:Unknown Perk/Power

I've been playing Origins on Black Ops 2 with my buddy and something popped up on his HUD. I have no clue what it is and can't find anything on the internet about it. It looks like a stone with an "M" in the center and has a wavy line on the left side of it. It's placed between the round symbol and the perk-a-cola symbols on his HUD. Any idea or link to what this could be would be awesome.
