This might be more of a product of ROTC programs raising their admission standards for prospective ROTC students in the wake of the current military drawdowns much like the raising of enlisting standards in the news for the same reasons.
It’s no different than what happened in the '90s as a result of the end of the Cold War and the massive RIF and the massive raising of recruitment standards or what tended to happen after wars/conflicts have ended.
Some older veterans I’ve known would be inclined to cite the old cynical accusation about the military branches prioritizing/“protecting” FSA cadets/graduates over graduates of other commissioning sources even though studies from the last few decades have found otherwise.
