Hand to gun fight lol. Beating people up lmao. But to be serious, Sam trained quite a while to do what he does. There is alot about his history in the books.
This, I'm not arguing with. I'm quite sure that's true.
Shall I just go through a rundown of what happens in each scenario against Big Boss?
Solid Snake vs. Big Boss
They punch, kick, and throw each other until Big Boss starts thinking about CQC, and begins blocking/countering all of Snake's attacks. Then he gets Snake's stamina down to 0 by doing this, winning.
Big Boss wins!
The Punisher vs. Big Boss
Honestly, I don't know.
(wikipedia, wikipedia)
Well, it looks like he's overall awesome, and is probably actually better than Big Boss at hand-to-hand, and was forced into being better at hand-to-hand due to not having an awesome silenced tranq gun.
But the Boss has CQC, and can easily break arms/throw people/grab people from the front into a chokehold and break their necks/punch people/kick people
Don't know! But The Punisher probably wins against Solid Snake
Sam Fisher vs. Big Boss
While Sam Fisher has extensive training and skill in hand-to-hand combat(he was in the military), he has only had extensive development in
standard combat. CQC has had extensive development in itself. The only thing harder to beat than tons of hand-to-hand training is tons of hand-to-hand training using a hand-to-hand style that tons of time was spent into making. The only reason CQC exists is because standard military hand-to-hand wasn't good enough for The Boss and The Big Boss.
Big Boss wins, but it was close. He loses against Snake, too, because he only lost due to CQC's existence.
And Sam Fisher got into a hand-to-gun fight and beat the gun-wielder up? You wouldn't believe how many times that's happened to the Snakes (at least, in my playthroughs. I use CQC a lot in those games, and I tend to get spotted.)
Although, the Snakes do seem to have some odd tendency to survive gunshots, being run over, and nuclear explosions...teh haxors???
