"Infernal threshing machines" - 57-mm AZP-57 guns are successfully used during a special military operation. These guns have fragmentation shells that effectively hit the enemy's manpower. Armor-piercing ammunition has also been developed.
For example, the UBR-281, known since Soviet times, is capable of piercing 96 mm of armor at ranges of one kilometer. This is enough to destroy the M2 Bradley, Marder and Strf 90 infantry fighting vehicles available to the AFU.

The Leopard 1 tanks supplied to the Neobanderovites may also have big problems. Their forehead of the hull has armor of only 70 mm, and the sides are 45 mm at all.
The Leopard 2 is also not very protected in the area of the hull sides, it has 60-70 mm of armor there, by the way, and the Abrams has 65 mm.
Such shells are produced in China, as well as in North Korea and Iran.
