Please, please, don't pass up the opportunity to go to UVA for the Citadel.
I graduated from UVA last year, so I can give you some perspective on how NROTC works in the school.
You obviously won't have the same level of military commitments that you would have at the Citadel. After your indoc week, you'll have commitments a few times a week at the Unit. You'll wear your uniform once a week, attend lectures and classes every Tuesday, take an ROTC class, and work out with the unit a few times a week. If you're a Marine Option, you'll do some extra stuff to get you prepared for OCS.
The school has a good attitude toward the ROTC units with a few exceptions. You'll find people that stop you walking down the street and thank you, or the awesome lady who checks you into the dining hall who hugs you and tells you how proud she is of what you're doing. You also might get stopped at drill one morning and screamed at by a guy who works in the library, but in the end that's just pretty entertaining.
To echo the advice earlier, make sure you can function on your own. The ROTC unit isn't going to babysit you, and you have to be able to keep your own schedule and motivate yourself. It can be much harder then you think. If you can, you can have a great military experience with the ROTC unit, and a great college experience at UVA.
If you want a more specific breakdown of what you'll do at UVA, PM me and I'll give you more details.
Please, please, don't pass up the opportunity to go to UVA for the Citadel.
Very true....the experience was worth all of the pain and I have no regrets....not even for the tours I marched for running a knob out.Different strokes, different folks.......
