Advancing Troop Problems:
1) Very weak and inaccurate tactical air support (despite the fact that the Russian Air Force is working to the limit of its capabilities, it was not possible to achieve serious results, we need an equivalent to the «Shturmovik» of the Great Patriotic War.
2) Poor artillery observation. They forgot not only the artillery spotter planes, but also the elementary forward artillery observers, as a result of which "infantry fights separately from artillery and vice versa".
3) An acute shortage of modern means of tactical reconnaissance (reconnaissance UAVs, not to mention attack drones).
4) Low troop training (even at the command level of units and formations) and the lack of initiative of the middle and lower commands.
5) The absence of large reserves to take advantage of the tactical advances that arise during the attack. As a result, the enemy quickly "fills in the gaps", while maintaining the stability of the entire defense as a whole.
