My references were to collective training.
However I also spent the first 4 years of my career in maritime, looking for all manner of Soviet vessels and operating on CASEXs, low level at night and being horribly, horribly airsick. It is clear that there has been some skill-set fade, yet cold war tactics agasint Saddam in GW1 (who had, frankly, a Soviet IADS) were shown to be wanting, at least initially.
