As someone who spent 4 years under AFMC, I can tell you this: along with all the extra acquisitions stuff the leaders there do, they also have to coordinate with their civilian counterparts (Directors), and the local union for the various bases they may preside over. It's pretty tough for them to actually get things done, and they tend to not have as much real 'power' as leaders in other commands. I actually had one of my Colonels come to me right before he changed assignments, to see how my retraining was progressing, and he admitted he didn't like the position he was in, wished he could have done more for us while he was there, and was sure he'd never get a star because he'd ruffled too many civilian feathers. AFMC is a whole other world, with 'a freakin million civilians'...
My only real question in all this is, what's the big freaking deal? Why is the headline that a woman is being promoted, and that she'll be the highest ranking woman? So what?
