Duh. Because the Bundeswehr cannot shoot them down.

They don’t have the means.

Russian spy drones over Germany: Why the Bundeswehr cannot shoot them down – Russia uses surveillance drones over eastern Germany to monitor Western arms deliveries to Ukraine. German authorities are struggling to counter these espionage activities.

Russian surveillance drones are conducting reconnaissance flights over eastern Germany to track arms shipments to Ukraine, with over 530 drone sightings recorded in the first three months of this year alone, according to Western intelligence services.

They track the ever-changing routes of European military transports to identify which weapons will soon reach Ukraine, where new war equipment will be delivered, and when new ammunition will arrive at the front.
