Robert Green served for20 years in the Royal Navy from 1962-82. As a Fleet Air Arm observer/ bombardier-navigator, he flew in Buccaneer nuclear strike aircraft and anti-submarine helicopters. On promotion to Commander in 1978, he worked in the Ministry of Defence before his final appointments as Staff Officer (Intelligence) to the Commander-in-Chief Fleet. Having taken voluntary redundancy in 1981, he was released after the 1982 Falklands War, and trained as a roof thatcher in Dorset. In 1984, the murder of his beloved aunt and mentor Hilda Murrell led him to examine and then challenge the hazards of nuclear electricity generation. This, plus the break-up of the Soviet Union, followed by the 1991 Gulf War caused him to speak out against nuclear weapons, the first ex-Commander with nuclear weapons experience to do so."
