Nooooo, the only reason they Ukrainians have got away with LI tactics at the start of the war was because they were well dug in defensive positions, and the Russians completely forgot that All Arms means All Arms, penny packets of Armour operating without infantry support, and vice versa leads to a lot of dead bodies and broken steel. Incompetent doesn't even begin to describe Russian tactics
The Russo-Ukrainian War has reinforced the imporatance of the All Arms Unit, and the need for Artillary, lots of Artillary, and maintennace, and good log chains, and precison munitions that work. If anyone thinks otherwise, they haven't been paying attention
