conversation script could be better written. The main character, Frank Sheeran, is basically a snobbish coward whose only skill is to ambush assassin people, for money or just because he is scared of his own life by someone threat him if he does not do the assassin. He has no morality or loyalty, has zero courage to stand up as any man. The frequent reference of him to his military service is a sarcastic joke because his coward behaviour has nothing, has no relation to any military training in the world since there is mankind history. He is basically a thug anyway you look at him.
