My only contribution to this is the realisation, when the wall came down, what utter cr@p the Warsaw Pact Met. services were. Dreadful equipment, dreadful training, dreadful lack of ability. These, combined with the automatic loss of data to the Pact from the NATO countries once matters became tense ...... TTW, meant that their ops. would be in a very data-sparse area.
The higher formation forecast offices of NATO routinely produced detaled forecasts for nominated airfields of the Pact, and these were compared to the subsequent actuals. The results were the basis of an informal competition between the nations: MMO JHQ always came first. We were confident that some semblance of good advice could be maintained until we disappeared in a cloud of radioactive dust. Fortunately we were never tested.
