Ahh dude,they were put in the game bacause they are real...it's all stuff for the future soldier program that was started about about 8 years ago in response to Iraq. Before that it was the cold war the drove tech, if we went from the cold war right into a third world war(Like what this RP is about) we would have better tech then that. I'm military dude...I know a lot about this stuff cause I've seen a lot of it.
