Yes they do, but many of them are nowhere near as shitty as the boat, there are often careerist Officers who voluntarily take these "opportunities to excel" and there is a FAR better chance of flying your entire contract in the Air Force. I had many colleagues who did just that when I was in their world. It is virtually impossible to do that in non-tacair Naval Aviation.
Yes and no. There may be more opportunity to fly but that opportunity also includes flying from a container in the Nevada desert. Hundreds of USAF pilots have been drafted to fly UAV's and many have never left. Some of the luckier ones were pulled out of their original platforms after just a year or two to fly C-12's or U-28's. Then there was TAMI-21, a disaster to pilot morale that is still bemoaned 10 years later. Most of the ones you flew with were the lucky ones.
Every service has their shit sandwiches, doesn't matter much if they come in different flavors.
