Last time I was in that bit of sky (in a AN124 & IL76) flying into the Afgan/Kabul FIR it was under the control of a USAF/RAF E-3. Mission numbers were allocated to commercial traffic bound for Kabul/Bagram etc. Spirraling in from 15000ft into Kabul in a 124 for a TAC landing was just awesome, even better when sat in the glass nose of the 76!
