To the op, this is the sort of question I would expect from a 14 year old boy.
Totally different things.
Special ops guys won't usually beat egotistical cage fighters with tattoos and Mohawks and other bullshit in a fistfight, however they definitely have way more courage - because they know there is no referee to stop the fight. These egomaniac cage fighters (excluding the Japanese and Ruskis for the most part) need their ego fed and have a strong sense of self preservation that would preventing them from really 'putting it all on the line'.
