Hell - most of us who're in longer than a decade ago HAVE seen it.
Anybody here remember courses BEFORE the Human Rights Act? Back when they could and did occasionally strike you, insult your parentage, etcetera?
Anybody here remember a Church Parade?
Remember when you weren't ALLOWED to read the CFAOs or QR&Os?
Just a couple of things that came immediately to mind. The culture IS changing, HAS been changing, and will CONTINUE to change. For the most part, it won't be noticeable to anyone still serving, as they'll be changing along with it.
