I wish we had DX'ers in the military. Life would be much easier. Really only applicable for a cross country flight, rather than a typical local area sortie where you takeoff and land at the same place and fly a canned IFR route to the SUA. But on those cross countries or ferry flights, its all on us. Which means basically "hey new guy, go find us a route, file it, get the weather brief, pull the notams, grab us all the approach plate books we'll need for everyone in the flight, load all the mission cards, make the kneeboard cards, call the airports and make sure they have contract gas (and PPRs for any mil field), and we'll see you in the morning at the brief"

What could go wrong haha.....
actually, normally they do just fine with all of this. I've never had an experience where whoever did the planning had anything to do with why it went sideways. We've got no ACARS, and the first time you know that a field has deteriorated below the forecast and is no longer legal, is about 100 miles or so when you can start picking up the ATIS. And then it is a really fun phone game with ATC trying to figure out where the hell to go with none of the information at your fingertips (no iPads).
