There are two main tracks in the AF, bomber/cargo/tankers get have a much larger emphasis on gliding as fighter’s really can't glide for crap.

The AF does promote people learning more general skills in their free time, but fighter jets are very special aircraft and that tracks focus is defiantly on becoming a better fighter pilot not just a well rounded pilot.
