said to a solider something along the lines. Solider can you please escort the princess to her room. That is not the way a captain talk to his subordinate.
Well, a captain probably
would talk to his subordinate that way. Especially in a pre-modern military. But it's all in the question of tone.
Put emphasis on those words in one way, and it sounds like plaintive pleading. Like you're basically begging the person to obey because you lack the authority to compel their obedience. Reading it that way makes him feel like kind of a bitch.
But those same words, said in a different way, can take on a tone of command. Say it in the voice of someone who is accustomed to being obeyed and who knows you're going to do
exactly what he told you to do even if he's phrasing it like a request, and it makes the speaker feel more like a quiet badass. Someone who is
so in command of their situation and environment that they don't feel the need to try and be aggressive or abrupt. Someone who is making it sound like he's asking because it sounds polite - but you both know he
isn't asking.
Commanding officers
can be polite to their subordinates. Even moreso when they're self-confident enough to know they're going to be obeyed. Needless dictatorial command is more the province of weak, petty men.
