Consider the weaponry, physical and mental abilities, strength and utility items of the soldier. Personally, I pick Doomguy. He's fast enough to outrun his own rockets, strong enough to punch his way through his enemies, and of course, he has the BFG.
EDIT:
For the purposes at hand, a soldier can be defined as a being who has at some point served in or for an organized military force. I'm not trying to start an argument, I'm just curious as to what a lot of Escapists think.
