I think the make up of the person is the primary driver here and I don't know that any of us can alter who or what we are. Some folks are just laid back and are able to think through and/or deal with anything that comes their way. Others loose control of just about everything including bodily functions. I don't know how you change that or even if you can. Those of you that have been in the military, particularly in combat, probably understand this better than anyone. All of you go through tons of training and when push comes to shove some perform well and others can't perform. It's just part of who we are.
Having said that, I'm been granted the ability to not panic. I've not been in combat but I have had one or two hair raising moments and I was pretty calm and able to think through what I needed to do. My wife is an RN and has about the same makeup. It takes a lot to rattle her.
I think everything you listed is good stuff and there are no doubt real time benefits from the training. Both in terms of skills learned and unit cohesion. I'm not certain it impacts who you are, though. And I don't know of anything that will let you learn who you are except the real thing.
I look forward to hearing YOUR thoughts.
