Crown Prince Christian of Denmark is suiting up for duty as he begins a new military training course.
On Aug. 14, the future king of Denmark, 19, was photographed participating in the Danish Armed Forces’ Lieutenant’s Training Course at Antvorskov Guard Hussar Barracks in Slagelse, Denmark, where he wore a camouflage uniform.
Crown Prince Christian is the eldest son of King Frederik and Queen Mary and his father’s future successor. It’s traditional across many of the royal houses of Europe for the heir to the throne to undertake military training, and Christian began his military service with the Guard Hussar Regiment in February.

A May statement from the Danish Royal House announced that the Crown Prince was officially a Guards Hussar and had been admitted to the Lieutenant’s Training Course, starting in August. The program lasts one year and is followed by a period of practical service as a platoon leader.
Before the Lieutenant’s Training Course began, the young royal had time off for some summer fun. Multiple outlets reported that Crown Prince Christian was spotted at Smukfest in Skanderborg on Aug. 8, appearing at the music festival that his sister, Princess Isabella, 18, also attended.

King Frederik, 57, and Queen Mary, 53, are parents to Crown Prince Christian, Princess Isabella and twins Prince Vincent and Princess Josephine, 14, and their children’s lives are balanced out by royal duty and schooling.
Crown Prince Christian began his military training after graduating from Ordrup Gymnasium in June 2024 and embarking on an extended stay in East Africa, where he worked on a farm.
Christian’s farm stay was reminiscent of another royal’s similar trip, as Prince Harry worked on a farm in Australia after graduating from Eton in 2003 and before starting Sandhurst.
