@ Kikapu:
here's what I found
https://www.defensehere.com/en/federal- ... nd-systemshttps://www.youtube.com/watch?v=pQ1lVhKc644It's all about Russian systems, nothing of western ones, so I am still puzzled how the Ukrainians have such a system.
btw the use of the "agriculture vehicle" was today reported in various channels, they say the Russians record the route the Ukrainians move, let them go on, and THEN seed the back of the route with mines. Then start shelling, the Ukrainians will either get destroyed by artillery, or enter regular mine fields, with no other option than retreat, using the same route they came from, thus receiving a surprise party with presents.
