Poland has moved 40,000 troops to their border with Russia, in anticipation of joint Russian and Belerusian military exercises.

Multiple independent sources from early September 2025 confirm that Poland moved approximately 40,000 soldiers to its eastern border, primarily with Belarus but also relevant to the border with Russia, as a precautionary measure ahead of the large-scale Zapad 2025 military drills conducted jointly by Russia and Belarus. This troop deployment is part of Poland's broader security response amid heightened tensions following incidents such as drone incursions into Polish airspace and concerns over regional stability.

Additionally, Poland announced closing its border crossings with Belarus during the exercises to enhance security. The sources consistently report the troop numbers and timing, linking them directly to the upcoming Zapad drills and related security concerns.
