Modern Warfare 2 has an MGS5-style inflatable dummy

gamesradar.com:

Modern Warfare 2 multiplayer will have a ton of new equipment and field upgrades that run the gamut from sensible to flat-out ridiculous. During a hands-off preview last week, Infinity Ward showed off some of the gadgets you'll be able to bring onto the battlefield when Call of Duty: Modern Warfare 2 drops on October 28, and it certainly seems like this is going to be the wildest Call of Duty game yet.

The biggest stand-out was an inflatable decoy that is a human-sized Kevlar dummy, not unlike the Active Decoy from Metal Gear Solid 5. We don't have images for it, but I can best describe it as a giant, feature-less humanoid attached in multiple places to a small circular base. Just like in MGS5, "it inflates rapidly, like you can imagine a car airbag," co-design director of multiplayer Joe Cecot says during the presentation. "It works in two ways: you can throw it down and then you trigger it - you can throw it on a rooftop, trigger it, it pops up and you can see people shoot at it, and then you can engage them. Or you can throw it down near a bomb site where you know players are gonna come by and as soon as they get close it auto-deploys."

This thing is going to scare the crap out of me in multiplayer matches, I just know it. And even though it looks sort of like a potato version of a soldier, Infinity Ward swears it fools players during testing all the time - even when it was just a deployable gray box that had yet to be rendered. The inflatable decoy can also deploy at different heights for added realism: if it pops up under a tableau, it'll be crouched. And if you throw it in the water, it pulls a swimming pose. 

The inflatable decoy joins other wild equipment like a drill charge, which bores holes in walls and drops
