Me and my fiance are in Korea and want to get married?

We are both stationed in Korea with the army. We want to get married and he says its up to me i want to get married now in a courthouse or something and then when we get home next month have a ceremony with the family like a second wedding i guess you would say. How easy is it to do or is it even possible. Please keep your rude and mean comments to yourself i am just asking for information
