Commander in Chief of the Army
After completing his studies in humanities, before he was Grand Duke, Prince Henri underwent military training at the Royal Military Academy of Sandhurst in Great Britain. He was commissioned as an officer in 1975.
He has the title of General.
You've probably seen photos of the Grand Duke in the khaki uniform of the Luxembourg army. For example, on National Day, when he attends the military parade. At gala dinners, he wears a black ceremonial uniform and carries a sabre.
