Crown Princess Victoria of Sweden joins Marine Regiment for exercise as she continues special officer training

Crown Princess Victoria of Sweden was snapped getting stuck into a military training exercise in Stockholm today.

The royal, 47, who was seen smiling in some images, showed she was not afraid to get her hands dirty as she joined the 1st Marine Regiment.

Dressed in military gear, the heir to the Swedish throne was seen holding a large gun as she attended the training event at the Berga Naval Base in Stockholm.

She was also seen posing alongside others in the 1st Marine Regiment for a group photograph.

As heir to the Swedish throne, Princess Victoria is currently undertaking special officer training in preparation for her role as head of state.

She has been snapped attending other training events, including a classroom-based war games lesson at the Swedish Defence University last month.

For her training today, in what appeared to be snowy conditions, mother-of-two Victoria wore camouflage gear, topped with a heavy vest.

She donned military boots and wore a baseball-style cap, as she sensibly opted to go make-up free, and pull her hair into a practical low ponytail. 

It was announced in April that the Crown Princess would undertake special officer training during the autumn months.

According to a statement released by the Royal Court on Instagram, the purpose of her training is to 'acquire a deeper understanding of tactics, military science, and military strategy'.

Speaking about her plans, Victoria said in the statement: 'My ambition is now to put all my energy into officer training in order to be able to represent Sweden and the Armed Forces in the best possible way in the future.

'I'm looking forward to an interesting and rewarding study time with my new classmates.'

This isn't the first time Princess Victoria has undertaken a military-focused course of study.

In 2003, she enrolled for a three-week basic training program at the Swedish Armed Forces International Centre.

Once Victoria becomes Queen, it is thought that her eldest child, Princess Estelle, will also have to complete the same tuition as second-in-line to the throne.

Like Victoria, other European royals have also embarked on similar military training programs in recent years.

The Crown Princess Leonor of Spain, 18, began a rigorous, three-year course at the General Military Academy of Zaragoza in Northern Spain last year.

She was moved to a naval academy in her second year, as Leonor seeks to acquire a holistic education about Spain's armed forces.

For her third and final year, the princess will study at the General Air Academy to round out the program.

Today's appearance came after Victoria attended an event celebrating the 100th anniversary of a women's voluntary organisation on Saturday.

The royal was all smiles as she arrived at Skogshem & Wijk in Lidingö for the celebration, which marks a century of the nation's Women's Voluntary Defence Organisation.  

She looked smart in a beret featuring a gold medal and a dark blue suit jacket and skirt, which is understood to be associated with the group being commemorated.

Her hair was swept back into a sleek up-do, while she kept her make-up simple and clean. Victoria completed her ensemble with a simple white blouse, and carried a bouquet of white, yellow and blue flowers. 

Photos from the event saw the royal warmly greeting other attendees, before also making a speech.

The Swedish Women's Voluntary Defence Organisation is 'Sweden's largest defence organisation open only to women', known as the Svenska Lottakåren (SLK).

The organisation, which says it is non-political and all based on voluntary contribution, was created in 1924.
