 So I believe we went through phases, I remember, all throughout my time and I went to every level of enlisted PME and then some. We went through phases where we've had doctrine and those types of topics in our PME programs and then we take it out for other leadership challenges. There was a time, I was a PME instructor and we had doctrine stuff in the curriculum but it wasn't testable and if anybody was anything like me if it wasn't testable I probably wouldn't spend a lot of time thinking about it if I didn't need it to graduate. So again I think if we could find the right level of understanding that airmen need to have about doctrine and put it in our education systems whether it's professional military education, in our tech training and other advanced training from a functional standpoint. But I also believe it's important that we make it easy to understand, we make it easily digestible, short five to seven minute videos. Most of our airmen today, they do most of the learning, hell I do most of my learning, I was flying down here last night at midnight watching YouTube clips on how to improve my golf swing. So if we could take advantage of the technology that's available to us and the way that airmen learn, so getting the content right is one thing but having the right platforms that airmen are going to be attracted to that they would spend time with I think is even more important. So PME again is just a small part of it because we enlisted airmen only get a PME experience every six to seven years between ALS, NC Academy, Senior NC Academy and beyond. So there's lots of time in there for other opportunities to teach. But like I said, they need to be short and sweet and easily digestible for our airmen to be able to take advantage of.
