The UK is sending a new anti-drone weapon to Ukraine. Called the "Rapid Destroyer" it is an electronic warfare unit, sends out electromagnetic waves designed to disable drones. Causes all electronics on drones to cease thus rendering the drone dead. Has a limited range, up to about 1 km (.6 miles), but does cover a wide swath so a swarm of drones can be bought down with one burst of the electromagnetic wave. Mounted on a truck for mobility and quick redeployment. It has been field-tested in Ukraine, and it worked. The Brits are sending 8 of these units just as soon as they are built.
The modern battlefield has forever changed. The US needs to remain on the cutting edge of military technology.
