What does someone who is in the Army do when there is no war at the present moment? And I mean someone who's actively in the Army, not like someone who went to boot camp but is working another job.

It's a relatively young (26 years old) character, female and enlisted from 18.

Also, are there some restrictions on what someone in this situation could do in their free time (like they couldn't go to the pool or date or partake in alcohol drinking...)

One more thing, just to be sure, you can be openly gay and serving in the military in the United States now, right?
