As promised I am going to conclude this thread with my post about Авиабаза 1521, Мары - Центр боевого применения | Airbase 1521, Mary - Combat Operations Center which was based in Mary-1.
This airbase is included in the general Afghanistan map area and would be a huge asset and incentive for the map's additional support by the community if it would be modelled.
1521st unit based at the Mary-1 was the Soviet analogue of the U.S.A. Top Gun/ Aggressors! It was a special base for training front line fighters in various ways on top of the training they were getting in their own airbases. (Training program code name "Operation Kavkaz" or "Exercise 500")
This training program for dogfighting and other combat flying, was not done in one day.
It lasted several weeks or even a month. This program would have been impossible without rivals that were the visiting units.
Thus, the majority of units of the USSR fighters visited the Mary-1 for training.
Mary-1 “aggressors” were flying the following aircraft:
In the early 70s MiG-21PFM, SM, UM and in 1974 - MiG21Bis.
Since the fall of 1975, the 2nd squadron on the MiG23M/UB (non-woven blue with white edging, camouflage since 1979)
MiG-23MLD was flown since 1984,
The MiG-29 9.12 was adopted from 1989 for the 1st squadron and from 1991 for the 2nd squadron.
To make the resident instructor squadrons stand out during the exercises, some quick identification elements - “cognac stripes, shark mouths, Vikings and Hornet logos” were adopted since 1987. After 1992 and the dissolution of the Soviet Union the airbase was disbanded, some of the jets were returned to Russia and some stayed as part of the Turkmenistan Air Force.
