Well, there’s the problem! I was in a mixed unit, while there were dicks in that MOS, there were also the guys that worked and flew hard and even did their ground jobs. Those were the guys or guys like them mentioned upthread. Spent 18 of 21 in the Wing, never met guys like you mentioned. Careerists, yeah, butt sniffers, unfortunately yes. Liars rarely, but you can’t get by in the Corps, if you lie to the rest of the Corps.
In defense of the USMC, the CO & XO who lied were fired along with the maintenance officer once the General read the emails. And frankly, the vast majority of military officers were more open and honest than what I’ve encountered in the civilian world.
I did a tour with a Navy squadron. I worked part of the tour as the Safety Officer. Anything that didn’t reflect well on the squadron did not go above the CO level. That was very from my experience in USAF squadrons...but then, much of my flying experience was before 2001. By 2008, it seemed like things were going downhill fast, and my impression is that it has gone all to hell now.
My son was in the Army Guard and my daughter in the USMC as enlisted, and both swore the things I did in the 90s would have been career-ending for guys in 2010.
