What a disaster.
A Western army would launch airmobile assault forces into the rear of the AFU(always carried out in areas weakly or not defended by the enemy), carry out artillery attacks, then descend infantry landing forces(always within artillery range of the superior unit ) to carry out attacks from behind, after the infantry disembarked, the helicopters could perform other combat missions (combat support missions and logistical support missions, among others), all this coordination to provide support and conditions for the armored vehicles to be able to advance (a maneuver that the Russians are trying and losing dozens of armored vehicles).
I watched the video and it doesn't seem like a disaster outside of Oct 10-11 when they tried to 'coup de main' & close part of the salient with a massed armored thrust. Their counter-battery offensive did not suppress the enemy batteries enough.
The Russians have limited troop quality (penal assault companies, mobilized infantry units, etc.) and aren't using mounted airmobile forces, likely due to Ukrainian AA.
Overall it seems that nobody has figured out how to executive efficient, rapid and powerful combined arms operations with modern ISR, AA & PGMs yet, the troop quality and planning capability doesn't seem to be there.
