Overview

• The exercises moved into their active phase at the Fakhrabad training ground after an October 20 opening ceremony with contingents from Belarus, Kazakhstan, Kyrgyzstan, Russia and Tajikistan.
• Roughly 1,500 personnel and more than 200 pieces of equipment are involved, including six helicopters and over 20 unmanned aerial vehicles.
• Barrier 2025 debuts as a CSTO-wide formation for radiation, chemical and biological protection and medical support directly subordinated to the peacekeeping commander.
• The drills run October 20–24 to rehearse a peacekeeping mission on the territory of a CSTO member state, timed to coincide with the final stage of CIS Anti-Terror 2025.
