Brigadier Derek Mills-Roberts, CBE, DSO & Bar, MC (23 November 1908 – 1 October 1980) was a British commando who fought with the 1st Special Service Brigade during the Second World War. In a quirk of military history, he became the only Allied soldier to strike a German field marshal with the latter's own staff-of-office – when Mills-Roberts beat Erhard Milch over the head with the just-surrendered marshal's baton.
