i got the book Lone Survivor co-authored by the Navy SEAL who survived that gun battle in afghanistan years ago, after all his team had died. the SEAL who survived was my fraternity brother.
he probably could have. he (and his twin brother, also a SEAL) was a high degree black belt. very intense guy. i remember seeing them at hell week (where pledges gets hazed) when i was going through, but he graduated not long after i joined
