Not sure that Sledgehammer actually did that much research - they just thought up a bunch of futuristic concepts and threw them in the game without really learning how they worked (exosuits, railguns, 3D printers). Almost none of the futuristic tech in AW behaves remotely like it should in real life. There are some inspired concepts in the game but they're all pretty much pure fiction. Treyarch handled this field a lot better in BOII.
