Travel restrictions?

I know that after you commission, you have to get permission if you want to travel abroad during leave. But is it the same during ROTC? Hypothetically, if I wanted to go to Iraq during summer break (I'm not insane, just posing a hypothetical), is there anything stopping me beyond my common sense? I'm just trying to gauge the freedom aspect here. How much control do they have over these kinds of decisions?
