Sqn callsigns were used continuously in support of the No-Fly Zone over the Balkans throughout the 1990s. However, on the morning of the first NATO Air strikes after the fall of Srebrenica, some bright spark in CAOC decided to swap around all of the callsigns to "confuse the enemy". All it succeeded in doing was to confuse the Allies and destroy any situational awareness over the battlefield. No-one had a clue where anyone was and where other friendly assets were - especially when looking for Tankers and other support aircraft with aircrew habitually reverting to their usual callsigns. The situation lasted for a day, and normal service was resumed by next morning. Perhaps the most upset by this was the USAF fighter squadron who discovered in the morning tasking signals that they had been allocated the callsign "Faggot" . There were many reports of raised voices in the corridors of CAOC and other HQs with that one.
