Spurred by the war in Ukraine, growing numbers of Poles are joining volunteer paramilitary groups to get basic military training and prepare to defend their homeland from what some see as a looming Russian invasion.

The Polish government has kept its distance from the unofficial civilian militias but, with anxieties about Moscow's intentions growing, the professional military is now looking for ways to harness the volunteer groups.

There are an estimated 120 such groups in Poland, with total membership around 10,000. On Friday 800 members gathered in Warsaw at a meeting organized by the Defense Ministry, the first time they have been given official recognition.
