1. We don't really go to the field (save maybe an overnight once in a blue moon for range day or something). Day to day work is usually 9-5ish. As a junior warrant you'll be put in charge of something like the fridge to start, then after that ALSE, supply, flight ops, etc.
2. Duty stations covered above. There are a few more one off spots (like jets in japan or C-27s in Bragg/Yuma), but those are rare/impossible to get as your first duty station.
3. Promotion rates to CW3 are high. FW guys are more competitive going into the airlines/ISR contracting over seas so the Army is trying to throw everything at the guys around 6 years into their ADSO to keep them from leaving. They're currently offering a $105k bonus for a 3 year ADSO to any 155E (MC-12 pilot) with an upslip. You don't have to be tracked, or even a PC to be eligible for that bonus, that's how hard up the FW community is.
4. Advantages to FW would be: little/no field time/roughing it. TDY is spent in a hotel. Deployments are usually short. MAX 6 months but the norm is 2-4ish. Your hours in a FW platform transfer over better to the civilian side in most cases (airlines/ISR contracting). Also, there are tons of fun additional training opportunities such as: upset recovery training (aerobatics in an extra 300 and a jet), bush pilot course in Alaska, CTP/ATP paid for by the Army (your results may vary on that one), sea plane course, and any additional courses you may want for your additional duty (I'm a cyber/S6 guy by trade/degree and I've been to training and been certified in a number of cyber schools while serving as a pilot here).
Disadvantages: FW is not as engaging/stimulating/exciting as the rotary world. Take that for what it's worth. There's also not as much direct support of the guys on the ground (we can/do do it occasionally, but it's not our normal everyday deployed job). So I guess job fulfillment would/could be a drawback.
Hopefully this is a good rundown to help you out.
