Sort of, but not really. Being in SOCOM (special operations command) units, you'll often get extra training in the form of Additional Skill Modifiers. For instance I was a UAV Pilot trained to fly the Hunter TUAV who got put in a Shadow 200 TUAV unit. I went back to training for a few months and came back with a W2 ASI denoting Shadow 200 qualification. That made my job designation change from 96U to 96UW2, which depending on the role, can mean extra pay.

Generally socom operators get paid more due to hazard pay, which is a graded scale based on how likely you are to get maimed for life or killed. I can't speak for anyone but the US Army, but they only allow commissioned officers and warrant officers to fly helicopters. As a UAV pilot, I was in a group of the only enlisted pilots in the entire US Army. We were on the same flight status with the same awful yearly physicals of the helicopter / plane pilots.
