The phantom pain trailer from e3 Has a transport vehicle in it that looks like the IAV Stryker Those did not start being put into protype phase until 1999 or the late 90's and was not put into deployment until the year 2002. So in other words the game is trying to be somewhat accurate to the time period and they screwed up or kojima is fucking with everybody minds on what time this takes place, or they just don't care and put it in anyway or it is a made up rip off. but what isn't? why bother to make everything else look correct for the time if they are going to just throw anything they want in?
he also has a robot arm so what ever kojima.
