It only makes sense if it makes sense to you. Presuming that your ultimate goal is to serve as a commissioned officer, there are different paths. You don’t mention if you’re in ROTC, but if you are, you’d be halfway there by the time R-Day rolls around. Do you want to start over and wait another four years? If you’re not in ROTC, you can still join and even win a sideload scholarship for your last two years. And then there’s OCS after you graduate. It really comes down to your goal and how quickly you want to achieve it.
