Skrunda, Latvia (AFP) — When war erupted in Ukraine, the head of Latvia's fashion chamber Dita Danosa did not hesitate to become an army reservist, swapping her usually stylish clothes for military fatigues.

"I really felt I couldn't be passive and just watch television," the 49-year-old told AFP at the Mezaine military training ground in western Latvia.

"So I decided, yes, the national guard was the place for me."

Since Russian forces invaded Ukraine in February, Baltic states like Latvia — which shares a border with Russia — are anxious about what Moscow might do next.

This fear has led to a four-fold increase in volunteers, like Danosa, for the army's reserve force known as the national guard or Zemessardze in Latvian.

"When the war started, all European values were endangered," Danosa said, punctuating the silence between the bursts of two bullets.

While Latvia's EU and NATO membership reassured her, Danosa said she felt under threat "because Russian aggression is unpredictable and we don't know what can happen."

Dressed in full combat clothing, including a magazine belt, she recalled that Latvia has a "history of occupation." The former Soviet republic regained its independence in 1991.

Mezaine's location is symbolic. During the Cold War, it was home to the Skrunda-1 radar station, whose two large installations were to alert the Soviet Red Army in the event of a missile attack from the West.

Now the area is used for, among other things, urban guerrilla training.

4,000 applicants

Created in 1991, the national guard is the largest component of armed forces in the country of 1.85 million people.

Made up of some 9,600 volunteers, it is divided into four brigades. The national army meanwhile has around 6,000 professional soldiers.

The guard's commander-in -chief Egils Lescinskis hailed the "great increase" in volunteer interest and said fewer people were dropping out.

He said they had received around 4,000 applications since the beginning of 2022, up from around 1,000 candidates on average each year.

Around 20 percent of the volunteers this year are women.

The volunteers take part in 21 days of basic training, usually spread over seven weekends, after which they are ready to serve when called up.
