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