Lt. Commander Mike Dahlgren: You're a first rate X.O., Andy. A damn good submariner. I know the men like you. Lieutenant Andrew Tyler: I'd give my life for any one of them, sir. Lt. Commander Mike Dahlgren: I know you would. I'm not questioning your bravery. The question is: what about their lives? You and Mr. Emmett are good friends. You went to the Academy together. Would you be willing to sacrifice his life? Or what about some of the younger enlisted men? I know a lot of those guys look up to you like a big brother. You willing to lay their lives on the line? [Tyler hesitates to speak] Lt. Commander Mike Dahlgren: You see? you hesitate. But as a captain, you can't. You have to act. If you don't, you put the entire crew at risk. Now that's the job. It's not a science. You have to be able to make hard decisions based on imperfect information. Asking men to carry out orders that may result in their deaths. And if you're wrong, you suffer the consequences. If you're not prepared to make those decisions, without pause, without reflection, then you've got no business being a submarine captain.
