Obviously this is a little off subject from Star Wars, but I’m a real life Navy vet and have witnessed ship captains in action and have known a few personally. The reality is that a ship captain gets to take the 100% of the credit for the successes of his command, but also takes 100% of the blame when something goes wrong, no matter the circumstances. It’s just the way it is, and there are few jobs in the military and hardly any in civilian life with such razor sharp lines of accountability and responsibility.
It’s a lonely life, and many ship captains experience a career ceiling at O-5 or O-6 because they simply can’t live up to the high standards. This is especially true in peacetime, where there are few opportunities for captains to distinguish themselves in important operations, but plenty of opportunities for them to run ships aground, collide with other vessels, or get themselves involved in sexual harassment or some other bullshit.
