I can't speak to that example, but I can talk about my military experience (something that I just realized in another thread is a fairly interesting analogy to what's going on here).
I was in a unit who trained medical personnel ranging of all skill levels from still-in training medical clerks to special operations medical nco's, to medical unit commanders, doctors, nurses, etc..
The dynamic there was different than I see here. We certainly recognized that those spec ops guys were better soldiers than we'd ever hope to be.
They were the epitome of elite and we had the greatest respect for them. But when training was done, they'd be at the after-hours party with us and sitting at our tables and we'd all be talking about everything from our families to our various experiences in the military.
There was no sense from them that they had to belittle our training, or that we had to bow down to them for theirs. They respected the fact that we were all in the same service more than they were concerned about different levels of training. And those of us who weren't at that level respected the heck out of their capabilities, effort and training.
The only time I saw this not be the case was when someone with far less experience and training would take on a posture of being elite within the presence of those who truly where. The results of that were often humorous to those watching, but it basically amounted to polite, but matter-of-fact rebukes without any expression of derision.
Where I did see some derision was when doctors and nurses would presume that their external military training counted for something. That any of us cared that they went to medical school. But that would be akin in diving I suspect to someone thinking that how much money they had to buy gear with made a difference.
I had the honor of meeting a fellow who had earned an CMOH. I recall he spent all of his time asking other people about their careers and had very little interest in talking about his own.
My experience, in a nutshell, was that the best were perfectly ok with the idea that everyone starts somewhere, and that sometimes those with little (and even admittedly inadequate) training where happy where they were; and moreover, it was more than acceptable, it was right to take pride in being in the service without regard to how elite one's training.
