Probably mining with artillery.
Apparently the Ukes are playing that game also.
“Ukraine is firing an artillery shell that lays mines built to destroy tanks. The US has sent Ukraine over 10,000 of these rounds along with the 155 mm howitzers that fire them. These mine-laying artillery shells are designed to force desperate choices. The Russian troops defending the front lines”
Lies! All videos of burning Leopard Tanks ate Russian photoshopped of Russian Tanks. German tanks are fireproof and can not burn. Mines can not hurt them! No Ukrainian Tanks have been lost! Not one. All talk of such things is just Russian Propaganda. The victory advance continues Russians are fleeing in a panic, shooting their own people. Only a few Ukrainian freedom fighters have lost their lives. The attack is driving the Russians out of sacred Ukraine.
