You’ve now received plenty of information from a couple of our resident experts on ROTC. Seems that the next best step is to contact Cadet Command directly and get resolution from the primary authority, rather than continuing to fish here for a explanation (none of which are to your satisfaction).
Remember that there are two parties to this agreement. There’s you, and you understandably don’t want to do more than is absolutely necessary to gain your bachelors degree. And then there’s the Army, which has a system for training officers-to-be that follows a certain timeline. Ultimately, the needs of the Army — whatever they may be — will take precedence. There may be a point of compromise that you find. But if not, why not make the most of the situation by grabbing more education at the Army’s expense? Seems like a sound win-win.
