If you take the ROTC scholarship to UND, keep in mind that you'll be a commissioned officer. As a commissioned officer you are 1) a leader, 2) a soldier, 3) whatever staff job you are occupying at the time, and finally 4) an aviator.
I'll give you a brief rundown of my army career. Four-year ROTC scholarship (no flight training program), graduated, commissioned, flight school, then spent 2 years as a platoon leader. That's a long time to be a platoon leader, so in that respect I was very lucky. However, half of that time period was spent not flying, either due to not having aircraft or not being qualified (my unit upgraded from the AH-64A to the Longbow about 9 months after I arrived). So for all intents and purposes, I got a year as a flying platoon leader, which is about what all of my friends got. I spent 16 months after that as the battalion personnel/administrative officer, where I worked directly for the battalion commander and did paperwork all day. While in that job, I was lucky to fly once a week. I spent 6 months at the Captain's course/staff school, and then showed up at my next battalion. Only I got there 6 months early, so no flying there. That's when I really started working on my fixed wing flying (out of my own pocket). When the rest of the battalion showed up (to go through the Longbow conversion), I was assigned to be the logistics officer for the unit. After initial qualification, if I flew once every two weeks, I was lucky. I worked from 7am to 10pm at least 5 days a week (usually more) for a year, behind a desk in my windowless office, building spreadsheets and powerpoint briefings.
That last job is what compelled me to leave the army...well, that and an endless cycle of deployments. If I had stayed in, I would've commanded a flight company in combat, probably flown 800-1000 hours in a year of being deployed. But if you look at the life cycle of an army commissioned officer, you'll see that after company command comes at least another 6-10 years as a staff officer before you get to battalion command, the next time you're really flying again. And that's if you're lucky. Of course there are exceptions. I know people who, after their line company command, went back to Ft. Rucker and commanded the training company as an instructor pilot. One of my friends (we were platoon leaders together) went special ops aviation after his line company command, and he flies all over the world in black helicopters right now. There are other options out there if you go Army. Just know that the typical career path goes like this:
Lieutenant - platoon leader (1 yr), then company XO/battalion staff (2 yrs)
Captain - battalion staff (1 yr), captains course (6 mos), battalion staff (.5-1 yr), company command (1-1.5 yr), battalion or brigade staff (1-2 yr)
Major - Staff college (1 yr), battalion S3/XO (1-2 yrs), brigade staff (1-2 yrs)
Lt. Col - brigade/division staff (1-2 yrs), battalion command (2 yrs)
That takes you to 19 years. You've spent at best 4.5 years in operational flying positions.
If you're lucky enough to lead soldiers into combat, which is a very great honor, you can expect anywhere from 600-1000 hours for a 1 year tour.
Don't get me wrong - it sounds like I'm all down on the Army. I'm not. I gave it 7 years active duty, I was an Army brat, and I'm currently IRR (nondrilling reservist). I've been in the Army in one way or another since the day I was born. If it wasn't for the Army, I definitely wouldn't be where I am today. I've got a few more cliche's, but I'll spare you. The point I'm trying to make is that you need to fully investigate what you're getting into before you dive in. The scholarship is a great opportunity. Just make sure it's what you really want before you sign on the line.
