Lviv's Tech Evolution Aids Ukraine's War Efforts.

As Ukraine prepares for its major offensive, it is using old technology like wind-up phones to avoid detection by Russia's advanced electronic warfare systems. Russia's Zoopark radars, Zhitel vehicles, and Borisoglebsk-2 can locate artillery fire, detect and block radio frequencies, and disrupt satellite communications. Ukraine's army of drones is also facing challenges due to Russian interference. While Russia has more drones and advanced electronic warfare systems, Ukraine is still able to resist and innovate.
