Someone mantle kicked me in 2v2 but I pressed the button to counter it and gibbed them. No medal. So it doesn’t work both ways 
The Double, The Triple, The Quad, The Quint, Half a Dozen, 7 Deadly Shots - kill 2, 3, 4, 5, 6, 7 enemies (respectively) within 4 seconds
Getting it Done - Killed the Leader as the leader in Guardian
Lead by Example - killed 5 enemies as leader.
Get out of my Way - killed an enemy while holding flag
Goaline Hero - killed an enemy while they was scoring in Gridiron.
Oh ya that reminds me of one I have got very good at even on 4.
I Know Kung Fu - countered a mantle kick/grab.
I just looked at the ribbons for gears 4 - you know, when you used to be able to see which ones you have and what they meant. The gladiator ribbon: “Killed an enemy using the knife execution in an Execution or Warzone match”.
Well, I performed a knife execution on 2v2. Is 2v2 classed as execution because of execution rules? I’ll keep an eye out next time I manage to mantle kick and execute an unfortunate game pass noob.
It is cause ive got that ribbon even on 4’s 2v2
Yeah, definitely is. Got it again today.
Gladiator ribbon = execute opponent with the knife in a warzone or execution match (including 2v2)
The Ocho - Killed 8 enemies within four seconds of each other
I got a ribbon a few days ago called ‘10-56 in Progress’ which I think was kill an enemy while he’s executing a teammate.
So It’s Nomore Oscar Mike Huh ?? Smh 
I was wondering cause I just noscoped 3 enemies running towards me and I didn’t See nor get any Ribbon for it:triumph:I’m Like Wait Whatttt That should be 3 Fkn Oscar Mike’s
10-56 is damaging an enemy who commit suicide - something like that.
Also, old thread but headshotting someone holding a meatshield is the same ribbon as it was in 4.
