When getting picked up by a guard or reserve unit, one of the big benefits is you can kind of pick your airframe. Are you stuck with that forever, or are there opportunities to transition to other aircraft later in your career?

How are helicopter pilots seen from a rated perspective if they wanted to train into another airframe/unit later in their career? Are the rotary skills considered transferable to fixed wing?

Say, if I started in a reserves position in a HH-60, are there any opportunities to later fly something else at all?
