I'm not sure if this should be posted here, on writing, or somewhere else. But I am curious as to the procedure the navy (maybe like the US navy or even the British Royal Navy) would take after a serious event (such as the destruction of a major public transportation hub in a terrorist attack). More specifically, let's say one ship had an officer who advised a tactic that might seem suspicious and the captain ended up agreeing with it at the time and ordered the move. Would a hearing be immediately after that event or days/weeks/months later? Also to muddy the water up a little more, the action was not with rationale and had no apparent intention to assist the attack.
Just to note, the navy is an analog for a future space navy.
