Ain't nuthing new, back in "the day" we had AFR 30-1 Air Force Standards that came in a handy little pocket-sized version for the troops. I still have one, dated 4 May 1983, that laid down the law on how people were expected to act. Straightforward and to the point, none of this bullshit "culture" crap.
I also have a copy of AFP 35-49 Leadership that I carried as a lieutenant and junior captain. It was dated 1 September 1985 and was "a basic guide for the new and for the aspiring Air Force leader." It stated the USAF leadership concept centered around two fundamental elements: The mission and the people (in that order). It was something I would carry and occasionally dig out to read every once and a while.
Both would be good for today's young officers. Much more than this "culture" bullshit.
