This honorary role was created by RUSI's trustees and advisory council in recognition of General Petraeus' long association with the Institute and his distinguished contribution to the study and development of defence and international security concepts, as well as his implementation of those concepts in operations in the Balkans, Iraq, and Afghanistan. Earlier this year, General Petraeus was conferred RUSI's Chesney Gold Medal for his lifetime service to the field of security studies and operations.As the press release says, Petraeus was awarded RUSI's Chesney Gold Medal on June 10, 2013. In late 2012 the think tank had postponed the presentation of the award after he was involved in a sex scandal.
In May 2013, it was announced that Petraeus would head KKR & Co. LP's new global investment think tank - the KKR Global Institute.
