AMC '17s are hella busy right now, but the mission is great and you make a shit ton of money. I haven't owed taxes since 2007. My advice, OPS tempo changes all the time and could be totally different by the time you finish UPT and FTU, so take that for what it's worth when you make your choice. When we filled out our dream sheets, the word on the street from the C-17 world was still "you can fly as much or as little as you want to, copilots sometimes have to fight to get on trips". We all know how that's been working out lately, not that I would have chosen differently.
