How do you know that? Maybe back in 1940 or so, but much less now, and in the Marines, not at all.
Besides, the OP was asking whether he should pursue a flight slot in the Marines from USNA or Marine-Option NROTC. A lot of posts here, esp the suggestion of BDCP, are missing this. If the OP has the intellect to get into a decent civilian school with NROTC, then he should. If after a year he still has a hard-on for the academy, he can still apply there. I have a suspicion he won't, though.
yep. just looked it up-
only 8 from OCS total. last 2 were:
Admiral Vernon E. Clark, former CNO- Navy OCS class of Aug 1968
Admiral Jeremy Michael Boorda, former CNO- Navy OCS class of Aug 1962
Out of 246 Admirals since there was even a US Navy, "220 were commissioned via the U.S. Naval Academy, 14 via Naval Reserve Officer Training Corps, 8 via Officer Candidate School, and 4 via other sources."
i think this makes my point in black and white!
OP: think long-term. pick NAPS+USNA if you have the choice!
