I think it's really hard to decide between a Soldier and a Dragoon for you. Both have a strong sense of leadership, are a mix between calm and energetic though more on the calm side, loyal, hardworking, independent and honest. I'm going with Soldier in the end because even though you usually are withdrawn, you open up to a few chosen people and I know you as rather understanding and, unless someone provokes you, not really "gruff".
