Captain Imgram is a career officer, and bully. He is follow orders by-the-book no matter how wrong or right the orders are type of commander.
He does not question, only carries them out, but if the orders bring about some kind suffering to others, then Ingram does get hidden enjoyment from it. His loyalty is to the empire and the chain of command. He is cool under fire and a good poker player. Many times he can intimidate his opponent without firing a shot.
While he did serve during the Second Sabor War, his posting was on the other side of the empire, running peace keeping patrols around problem colonies to suppress any idea of succession from the empire when it was largely preoccupied with the Sabor campaign.
