Clearly a riot shield juggernaut suit. It too you hours of frame by frame? Wow.
Seems pretty weak if they aren't juggernauts. And OP if they can take a fair bit of damage... If IW's AI is as good as they say.
IIRC, there is supposed to be a Killstreak where the description says hide behind a guy with a Riot Shield. This could be it. It sounds like a bot with a Riot Shield.
Not really a new find it was shown in video. Just not talked about. They are not going to talk about or announce every streak in the game before it comes out or show what they do.
