More people ought to be concerned, but what you're seeing with the shift of Air Guard missions isn't just spreading them thinner. The last BRAC took the aircraft away from a lot of states and left them with UAV's, associate units, or nothing. I'm not sure if it's true, but somebody in the BRAC believed that you get more efficiency out of aircraft if you put them with both active duty and reserve units at the same time and at the same place. That's put a huge shift on the Air Guard. Nobody questions their commitment or competence, it's all about efficiency.
