Russian 'Courier' UGV with machine gun for anti-drone defense

The post claims Russia is deploying a remotely operated ground robot ('Kurьер/Courier') fitted with a machine gun to engage Ukrainian drones. It also claims one operator can control up to three units, presented as a response to paired drone raids where the robot covers the second drone while a human gunner engages the first. If accurate, this indicates a new/expanded use of armed UGVs for counter-UAS point defense and multi-UGV remote control at the tactical level.
