Best thing for my career in the AF was figuring out that email really wasn't that important. Servers, routers, switches, etc - not important of themselves, or because I worked on them. Before Comm went Ops the important stuff was the UAV video, ATO's, emergency orders and that sort of enabling that was our real mission.
We had a Wing CC - BG Wright, who's slogan was "Where are you in the kill chain". Sounds lame, especially since we were at Beale, but he pushed it and people started to come around and realize what the real mission was about. He'd do Sq tours and ask the Amn where they were and they'd have to answer.
I still think about it when I'm trying to explain to Senior Leaders that stuff, does in fact, just break and we can't tell them when it will happen or why, or how long it'll take to fix.
Especially blackberry's, damn those things to hell.
