Simon Francis Mann is a British mercenary and former officer in the SAS. He trained to be an officer at Sandhurst and was commissioned into the Scots Guards. He later became a member of the SAS. On leaving the military, he co-founded Sandline International with fellow ex-Scots Guards Colonel Tim Spicer in 1996. Sandline operated mostly in Angola and Sierra Leone, but a contract with the government of Papua New Guinea attracted a significant amount of negative publicity in what became known as the Sandline affair.
