Good answer, thanks a lot. I've missed the point that ROTC are not independent and their parental colleges may went pacifistic
And ultimately, ROTC has a committment of a few hours a week. If USNA/USMA/USAFA/USCGA/USMMA really wanted to, they can adjust their days to reflect the requirements of their services. While at USNA, I had access to ship simulators, small ships to con/OOD, sailboats, obstacle courses, endurance courses, Marine Corps Martial Arts courses, navigation charts, etc. USNA uses all of them to some degree, but I imagine it wouldn't be hard to cut out electives in degrees and add in more navigation or physical fitness courses or whatever else it needs for its graduates in upcoming years. Cases in point: when I first showed up to USNA, they started offering Arabic and Chinese as majors; and recently USNA just opened up a new cyber center and formalized its degree programs within that. They see that's part of the future of warfare and are ensuring they have some graduates able to fill those roles, which ultimately cannot be guaranteed from ROTC or OCS.
