In this timeline, Einstein went back in time to stop Hitler like he does in most universes....but this time he had a bite to eat first. Right as Einstein was going back to the future, someone threw a grenade at him. He blew up right at that moment. He made it back through but it glitched out the machine. It now makes many copies of him and fused his gun to his body. When using the gun his body morphs and is put back together again. A few other things have happened differently as well...like the creation of the giant ants piloted by humans and the super shroud technology. If a gap generator is low enough to the ground and just the right size (as in the small version on the truck)it creates an armor field around it....but this field can not be put on the rest of our tanks because it blocks weapons. Good luck, and may we defeat the Soviets!
