Taliban by name my be formed in 1992 (not 1994
) but all the major players of Taliban were known to those who were involve in soviet war.
In soviet war, mujahideen's were not organized to take over afghanistan, but was trained for Gorilla Warfare, that's why no organization name was know but some segregated elements only. But in 1992, Taliban name was given so that instead of gorilla fight, they become an organization against Russian backed government and Irani/Indian backed militants (which become North Alliance later on). But that doesn't means Taliban were not involve, it just means "No Taliban" name was used back than. Even I remember during soviet war, mujahideens who were getting trained in Madrass used to be called Talibs.
