well an average marine would be destroyed by fedor, or any good mma fighter. think about it, mma fighters train all day every day to fight. marines have been given training, but its not all they do. not to say there isnt some marine out there who's a badass motherf****r, but 99% of the marines would be ripped limb from limb.
