My son is the same with five active now. He has decided to stay and try to fix.
From what I read here, this is a top-down problem, unlikely to change unless we get into a real naval shooting war where competency is the standard, not political correctness. Lord help us all.
My young cousin is at four and a half years and has made his mind up to leave when his hitch is up. His wife is in the OCS program, though, so it looks like they'll remain a Navy family for some time to come, assuming she graduates as projected.
His daddy did a year and a half in the Camden as a USNR SK3 in Zumwalt's Navy, passing out bullets and beans on the Gun Line (I think he's fully qualified for membership in the Tonkin Gulf Yacht Club, but he never applied: He was afraid if he did, he'd wind up back in Olongapo somehow), and I was a Reservist JO in the Atlantic Fleet about the same time, did a total of about 2-1/2 years' active duty until the big Eddie Hebert RIF.
