An unnamed defense company from Israel supplies Ukraine with cannons to counter enemy drones. They do it via Poland.
Here's What We Know
This is reported by the Israeli publication Zman Yisrael. The company sends the cannons to Warsaw and pretends not to know how Poland will dispose them. This is done because Israel officially refuses to sell weapons to Ukraine.
The Israeli Defense Ministry could prohibit the delivery of guns to suppress unmanned aerial vehicles if it wanted to. However, journalists emphasize that the defense ministry also pretends not to know that Poland is transferring arms to Ukraine. The guns fall under a ban on deliveries to Ukraine because they are classified as advanced defensive technology.
Guns like these allow you to shoot down unmanned aerial vehicles, by creating interference on frequencies that are used by drones. The Armed Forces of Ukraine are already using futuristic DroneDefender guns at the front, which arrived from the USA.
