Col. Gaddafi was always surrounded by three permanent bodyguards. On every trip, they used accompany him. But for a foreign trip, Gaddafi used to take four additional bodyguards who were selected by Gaddafi himself.
They all had to be virgins and were sworn to chastity before becoming official bodyguards. Also, they were made to take an oath that they would give away their lives for Gaddafi's safety.
