Pogrom of Russian cannon howitzers

The Russians lost 5 of their modern 2S33 MSTA-SM2 cannon howitzers in Luhansk and Kharkiv regions a fewer days ago, which is simply a large failure for their army, considering that the full number of cannon howitzers in this standard is expected to not exceed 50. In total, since the beginning of the Russian invasion, the Russians have already lost 17 artillery systems in this standard.
