In fact, Frank Wisner, Director of the CIA covert action department Office of Policy Coordination (OPC), was setting up stay-behind secret armies across Western Europe and in his operations collaborated closely with the Special Operations branch of MI6 of Colonel Gubbins. The SAS and the American Green Berets, trained to carry out special missions clandestinely in enemy-held territory, were at numerous instances during the Cold War brothers-in-arms and among other operations also trained the secret stay-behind armies.

The SAS were disbanded at the end of the war in October 1945, but were quickly reborn in 1947 and used to fight behind enemy lines in Malaysia. In their biggest deployment since the Second World War, SAS units served in the Gulf in 1991 and together with the U.S. Green Berets secretly trained and equipped the Kosovo Liberation Army (KLA) forces before and during the 1999 NATO bombardments of the Serbian province of what was Yugoslavia at the time.[2]
