Nor was I saying there were USAF operations out of Russia, but airplanes do fly in Russia, and when they do, ATC gives them the altimeter calibration setting in QFE, unless at QNE altitude. :)
Altimeter setting isn't a preference of the Air Force, it's a mandatory flight rule. The "real world" example you can compare this to, is by looking at the Russian Federation flight rules, which the USAF would adhere to.
