Ukrainian tank crews actively use a standardized anti-drone protection device, informally known as a "hood."
It's a lightweight, foldable mesh screen that protects armored vehicles from both FPV drones and drone-dropped munitions. At the same time, it preserves visibility and enables the crew to exit the tank in case of emergency.

Meanwhile, in russia, where more massive and heavier solutions are typically used, the Ukrainian design was ultimately copied and even patented. This was pointed out by armored vehicle researcher Andriy Tarasenko.
At the same time, the stolen technology is being presented as an original invention by russia's central institution for engineering troops — the Karbyshev Military Engineering Academy. The russian patent contains a detailed description and all aspects of this technical solution.

It is noted that "research conducted during the development of the invention confirmed that, based on the criterion of combat effectiveness to cost, the proposed technical solution demonstrates performance 1.2 to 1.5 times higher than known analogues."

On the one hand, this is certainly a positive assessment of the Ukrainian developers' decision by the enemy. On the other hand, it means that russia may well try not only to patent this solution, but also to implement it in its armed forces.
In practice the solutions long used at russian armored vehicle factories for new, repaired and refurbished vehicles continue to be modified by the occupiers. As a result, russian tanks often have double "grills," factory-made and handmade.
