any people here that are curently enlisted?
What ever you want to know, PM me.
Normally here in the US, there are two in a room. In Germany on most installations it's two and three to a room. Years ago when I first went to Germany, it was 6 to a room like Russ said. Korea may still have the large open bays in some camps.
Things began to change in 1992. The Better Opportunities for Single Soldiers or BOSS program came into effect. With this, one can bring visitors to their rooms (yes, females visiting an all male unit).
If you are married going in as an enlisted man, it's financially difficult. There normally isn't enough housing on post, so you must live off post. And they don't pay you enough to live off post when you are in paygrades E1-E3. After E4, it's a bit easier. I have known E1s with working wives and no children who did relatively well financially.
It depends on the job or MOS you are in whether or not you can go to school on active duty. Combat arms: Not with any regularity, although there are exceptions. Took me four years to earn an Associates degree. If you are in something like personnel, administration, or something technical; then school is a possibility outside of the field/deployment.
For me, the biggest enjoyment was working with younger men when I was a Senior NCO. Helping them develop job related and cohesive skills.
Don't listen to everybody about being an officer. One must learn to follow before they can lead. Yes, it's great if it's not in a combat arms field (Infantry, Armor, Artillery, Combat Engineer, Air Defense Artillery). Personnel, finance, or something specialized is easy compared to combat arms. Most infantry officers I saw worked harder than the enlisted. Infantry company commanders work some insane hours. The good ones anyway. The best officers, in my opinion, were formerly enlisted. Again, the good ones.
One option is the reserves. Another is a 2 year, 17 week active duty obligation. With a college fund. But you'll most likely go combat arms with a 2 year enlistment. It's a good way to go to college. Be hardcore for a little while. The technical fields require longer enlistments. 4-6 years.
Out of 20 years, I was overseas for for a total of 12. Enjoyed Europe so much, I made a career out of the Army. Korea wasn't too bad, but I really didn't enjoy it. Then of course the deployments to the Sinai, Gulf, etc.
The Army isn't a bed of roses. It's tough, demanding and strict. Not for everyone. When you have finished your time, you know you've accomplished something to be proud of. By the same token, it's a lot of fun. If you go Infantry or Armor, it's a real trip shooting all those weapons. M16A2, SAW, M60, M2 .50 Cal, M203, mortars, 25mm (on a Bradley), 120mm on a tank.
After it's all said and done, I'm happy I joined and served so long. I miss the 30 days of leave every year. Now, I have a one week vacation from my current employer.

Just started a new job. I don't miss being away from my family for so long.
There's good and bad to go along with it.
