Russia Abandons One Of Its Most Advanced Electronic Warfare Systems
Ukraine has captured one of Russia's most advanced electronic warfare systems. The Krasukha-4 command module jams low-orbit satellites, drones and missiles, and can reportedly track NATO aircraft. It has a range of 186 miles and is designed to block airborne warning and control systems (AWACS) as well as protect Russian forces from surveillance systems.
The unit is split into two parts, a command post module and an electronic warfare system, which are mounted on two trucks.
Ukrainian forces stumbled across the device near Kyiv, and photos posted online show the large unit covered in branches, in what appears to have been an attempt by Russia to camouflage it.

I imagine they removed and/or destroyed anything of value.
