A long-serving military captain, Sterling has all the experience of war he will ever need. No-one knows more about war than he does but in truth, although he is tired of it, he has nothing else to do. His command style is that of tired authority.
He might not care if he lives or dies, but he’ll never go without a fight, just out of pure bloody mindedness.
With his crew, he gives orders in a manner that sounds relaxed but gives no doubt that the order must be followed. He does not repeat himself, he does not berate – he does not need to.
