I work with Marines everyday as a contractor now. My son is an active duty Marine. I know what Marines are thinking and saying. You give them less credit than they deserve. Marines now still do what Marines of the past did. They adapt and overcome.
The enlisted are fine. the leadership training them anf giving orders is the problem. Your sun must tell you about the SJW crap. Because the Marines are not immune. My USAF Sgt daughter left for that reason.
