An American newspaper talks about a “mystery” that puzzles Pentagon experts about the weakness of the weapons sent to Kiev forces in the face of Russia’s capabilities.

Business Insider reported, citing military analyst from the Center for a New American Security, Stacey Pettyjohn, that Pentagon experts are receiving information about weapons vulnerabilities in Ukraine.

The newspaper said, "Maneuvering, camouflaging and providing supplies to Russian forces on the battlefield under constant surveillance by drones is another puzzle facing Pentagon experts (in Ukraine) and has raised serious questions for Pentagon leaders."

She indicated that the United States receives information about the weak points of its weapons on the Ukrainian battlefields.

"Russian electronic warfare units are becoming increasingly adept at disabling the GPS navigation systems used to guide missiles and projectiles to their targets, knocking them off course and rendering them useless," she added.

Western media have repeatedly spoken about the effectiveness of Russian electronic warfare systems. The New York Times wrote that these systems are successfully used to destroy Ukrainian drones.
