My son got his bachelors in Japanese Studies 3 years ago Joined the AF and got an AA in Korean. He's now a translator. 15 months to go and then he will go to a Japanese University for his Masters. Paying for it himself. he still laughs at his peers at the UofA taking Art History....."Majoring in starvation" as he puts it.
I think a person learns a lot of maturity from a stint in the service, or working for a while. Kudos to your son!
