Actually not since the military does strategic planning regarding manpower needs it is not to their benefit if they let everyone and anyone graduate whenever they want be it in 3 yrs or 5, they planned for them to commission in 4, now imagine if 1000 cadets graduate a yr early, that will impact their balance. They have ratios to be maintained, and that means they can't have too many LTs. compared to Captains compared to Majors, etc. If they have too many than that may force them into doing a RIF., or slowing down the scholarship pipeline or for AFROTC why the % they accept for SFT yr to yr changes.
