From the riot-torn streets of Belfast to the frozen moors of the Falklands and the scorched deserts of Iraq, Royal Marine Commando Geoff Nordass has been an eye-witness to some of the bloodiest conflicts of the late twentieth century.

Joining the Commandos at just seventeen to prove himself worthy to be a member of 'the best of the best', Nordass found himself in an elite Arctic Warfare unit. He was mentioned in dispatches during the Falklands War, served in Hong Kong on border security missions with Communist China, completed two tours in Northern Ireland and repeated NATO winter warfare operations in Norway. By the time he left the Royal Marines, Nordass was a parachutist, a navy diver, a coxswain, a hovercraft specialist and had served in support of SBS special forces.

Retiring from the Royal Marines, his remarkable life took another twist as he worked as a bodyguard for Lady Diana Spencer's boyfriend, Dodi al-Fayed, before directing security operations on some of the world's most luxurious cruise liners. He later ran a private security mission in Iraq at the height of the insurgency, as comrades fell victim to suicide bombers, convoy ambushes and assassinations.

Commando is an epic story of courage, loyalty, endurance and loss - and a remarkable insight into one of world's most famous fighting regiments.
