I'm really late on this, but in case you're still around:
I'm currently at DLI studying a CAT IV language. I enlisted at the age of 26 with a bachelor's degree.
DLI is a great opportunity, and one of the best ways you can learn a language.
That's the good part.
Now here's the bad part. You're 26, so you're a bit older than the average recruit(although you'll see plenty of other soldiers in their mid to late 20 signing up as linguists, many with college, some with master's degrees.)
Well, I assume you have been living as an independent adult for a while now.
As of the last few months, IET soldiers have had some very strict rules imposed on them. 9 O'clock curfew, no alcohol, battle buddy required at all times(you would encounter this in basic...you basically need someone practically holding your hand wherever you go, or risk getting an Article 15).
This is all fine and well, since most AITs are several weeks to a couple months long. But as a linguist, you will find yourself as an IET soldier for up to 2 1/2 years..a good chunk of your contract. Needless to say, morale for Army IET soldiers at DLI is pretty low right now. Things used to be more relaxed here considering the already present stress levels and the length of the training, but that's not the case right now. Being an IET soldier at DLI is a pretty bleak..especially if you're in your 20s. It's a big culture shock to go from being an adult to not being able to drink a beer on a friday night, or even stroll down the sidewalk on your own without risking some trouble.
I couldn't think of joining any other branch besides the Army, no regrets enlisting. In this joint service environment, I'm proud to wear the Army uniform!
But for DLI, the Army's not the best place to be in...at least right now.
Negative stuff aside, DLI is still a great opportunity. Just be prepared for what you're getting into. You need to be focused, and a die hard student, and you need to be prepared to give up your life for a couple years, and accept that you're going to have a very G-rated lifestyle. As an DLI Army IET soldier, you will pretty much be a basic trainee for 2 1/2+ years.
