Lieutenant General Sir James Benjamin "Jim" Dutton, KCB, CBE, ADC (born 21 February 1954) is a retired Royal Marines officer. He held various staff positions in his early career, before commanding 40 Commando. As a brigadier, he held two high-level staff posts—the first at the Ministry of Defence in London, as Director of NATO policy, and the second as a British liaison to The Pentagon shortly after the September 11 attacks, where he was involved in the planning for the subsequent invasion of Afghanistan. A newspaper later pinpointed this as the moment when Dutton's career "took off".
