See: Juggernaut perkThat is most likely what it is.I don't get how everyone bitched about it in CoD 4-5, it did virtually nothing, and they just blamed their deaths on the 10 extra health or so.
You can survive a sniper shot that is normally 1 hit kill with Juggernaut.
If you look down near the ammo counter you see the Juggernaut icon, with a predator missile in line behind it, so I think it's a killstreak that gives you a Juggernaut suit. It's also a 14 killstreak so that would be reasonable.
yay! reskins!
