I'm a UH-60 driver in the Army (don't shoot). I received a letter from a high schooler asking me the differences of my airframe to yours, and figured I'd try to do a little research. I found a decent fact sheet, but figured I'd see if I could track down one of your operators to compare notes. It seems like most of the differences are in our avionics packages, and in-flight refuel capabilities (or our lack thereof), but first-hand info is always better.
Appreciate the help from any fellow rotor-heads.
