After the war, Davis was sent to Germany to oversee the establishment of the Royal Marines Demolition Unit along Rhine, intended to be a deterrent against the Soviets in the East. During the 1960s he was a company commander in 40 Commando deployed to the jungles of Borneo for the Indonesia–Malaysia confrontation. He led "Pugforce", an amalgam of Royal Marines, Ghurkhas, Sarawak Rangers and Iban trackers deep in the jungle and managed to capture several rebels.
