I can see where the Soldier votes are coming from and I considered Soldier for you but in the end I am leaning a bit more towards Dragoon. Your traits, many of your "either/or" answers and the overall tone of your application remind me more of Dragoon and because you are more introverted than extroverted and you mentioned that you usually don't share your feelings, serious and calm. confident, reserved, traits that really remind me of many Dragoon characters.
