I just started the game a few minutes ago. One minor thing respectfully passed on for consideration.
Options available to the MC so far involved more or less adhering to military protocol but he is getting the protocol wrong.
Military personnel doesn't salute indoors (or onboard) except when formally reporting to an officer, such as when called to the commander's office or...as in the case of the MC, when reporting to his new ship. A lieutenant in any branch of service in any nation would not order someone to salute him indoors/onboard since he would be breaching protocol, unless he were in his office and the lower rank was reporting to him.
A salute is maintained until the officer either returns the salute or tells you to drop it.
When reporting to a new ship, he shouldn't stop to chat with anyone. He needs to make a b-line to the commander of the ship and say, "Lieutenant MainCharacter reporting as ordered, sir." Salute and wait for the response. He is not free to go anywhere on the ship until the commander welcomes him aboard.
Just minor things vets notice when we see them done incorrectly in civilian life. Simple things like saluting or when to wear your hat become deeply ingrained and it's jarring when we see them misused, mishandled, or disrespected. But we know to a civilian, none of that means a thing. Just saying though...we notice.
