OK, my time goes back almost 20 years (if I had stayed in, I would retire in October. Damn fool me...) I attended DLI immediately after AIT (Interrogator school, Ft Huachuca, AZ) I took the 47 week Japanese course. This actually lasted 1 year with the Christmas break, etc. Graduated 1 day shy of 1 year from AIT grad. When I was there, with the exception of morning PT and occaisional CQ was actually a lot like college. After PT and breakfast, we went to class all day. Then back to the barracks for some home work and memorizing monologues. I was an E2, made E3 while there. I had an off post evening job (evening manager at a tinder box store, loved it) Weekends were mine to do whatever I wanted. Several times I resided off post for a week at a time house sitting for instructors that went on vacation. All of these "Priveleges" were, of course, dependent on maintaining high grades. Although we did not have any officers in my class (1 Marine Gunny, 1 SP5, 1 college boy E-4 and 3 of us that started out at E1) Officers were attending and had classes of their own. At this time, the govt felt it inappropriate for lower enlisted to see weakness in officers so wouldn't let the enlisted get better grades in the same class. (I.E. why is he an officer if I can do this better than him and I am just a lowly little private?) We even had a few officers spouses attending class (those assigned to diplomatic stations) All branches of govt use DLI. We had all 4 branches of military, a few FBI and a couple of CIA that I knew of. The length of the course depends on the difficulty of the language. Level 1 (spanish) is about 3 months. Level 4 (Chinese, Japanese) is 47 weeks. Russian, although a level 3 is still 47 weeks. Although I was able to maintain grades with my "extra curricular" activities, DLI is NOT an easy school. I was fortunate to have a natural ability to learn languages. Most important about DLI is to forget what you learned in english classes. I learned more about English studying Japanese than I ever learned in school. Just be warned, it is an extremely difficult school. It is not easy to get in and is more difficult to graduate. While I was there we had 2 suicides, not counting the one 1 week before I arrived. Remember, you have a test every day. You will be totally immersed in the language. After a few weeks, you will not use English at all in class. You will make some of the best friends you ever had in that class, establish some rivalries and may even make a few enemies jealous of grades. Also, do not expect to be able to speak natively upon graduation. Different languages are structured differently so this may not apply. I could go out in Japan and get along just fine with the public. I could discuss anything military with the troops. I learned and immense amount about the culture, but don't even think to ask me to describe an alternator or an air conditioning compressor. Japanese is too career specific in writing and terminology for that. It would take about 5 years of DLI to learn what they learn growing up. One of my favorite memories of DLI was sitting in the day room translating the movie "Shogun" for the people in my barracks. (had my back turned and they were testing me. Had a blast every night that week). If you can go, I strongly recommend it. Just be ready to study hard because you are mixing advanced college courses with the military stresses. Good luck.
