Thank you for your service,
I was stationed in Okinawa for a while, everyone I knew that went to South Korea complained so this was really cool to see! I think that is great if you enjoy translating! Always keep an eye on technology though. AI translations are getting more and more accurate, and with Augmented Reality growing we will eventually be seeing subtitles with translation in real-time holographic form. If anything I say go into that field if that is what you love to do, but while doing it, look into the tech side.
