 would say it depends. So I do believe that most airmen understand the linkage between what they do tactically. We discussed earlier whether they know it as doctrine, so they may not know it as formally as doctrine, but I do believe most airmen understand that what they do tactically every day, how it links into the greater operational mission of whatever wing or whatever unit they're assigned to. And oh by the way I think it's the responsibility of leaders. So from flight commanders to flight chiefs to chiefs and squadron commanders on up to help airmen understand hey this is why we do what we do and be realistic and and not patronizing with airmen. I always give this example I had a watched a commander tell a young airman the way you pitch mail is helping us put bombs on target in Afghanistan. No, no it's actually not right so you have to be realistic in certainly the further an airman is away from you know flight line operations the more challenging it is to get them to understand how their tactical doctrine fits into the larger operational picture but I think it can be done and and that means that we as all of us as leaders have to be you know educated about what doctrine is and what it's not and and understand ourselves how it ties how what we do every day ties into the larger operational mission so that we can teach it to our youngest airman.
