Danish women face being called up for military service when they turn eighteen through a lottery system

The new law was brought in as NATO countries increased defence spending amid security concerns and a growing Russian threat in Europe, in recent years.

Before now, women were allowed to partake in military service when they turned 18, but on a voluntary basis.

Since yesterday (July 1), both men and women who turn eighteen will have to register to be assessed for potential military service. Volunteers will be recruited first; however, the remaining numbers will be drawn through the lottery system.

Falling under the new jurisdiction as well is the period of conscription, which will rise from four months to 11 months.

Last year, around 4,700 Danish men and women underwent a short period of military service, and about 24% of them were female volunteers. The new rules on conscription are believed to see the overall number of young men and women participating in military service rise to 6,500 by 2033.

Neighbouring countries Sweden and Norway have already brought in conscription for women in recent years.

Additionally, the Danish government have announced an increase of 40.5bn Danish crowns (£4.3bn) in defence spending over the next five years to help meet NATO targets.

Colonel Kenneth Strom, head of the Danish military's conscription programme, claimed the change was "based on a political decision and a political agreement made by the parties," per the BBC.

He continued: "And obviously, it's based on the current security situation to get more combat power and have those skills that are needed for either the Army, Navy, Air Force or even the Special Operations Forces."
