The war in Ukraine, which has lasted for almost a year, provides analysts with a powerful origin of cognition about modern armed conflict, becoming, according to some, a marker of the changes taking place on the battlefield. Referring to R. Leonhard's explanation of information era warfare, [in the erstwhile section the application of the mass rule (principle of concentration of effort)] is discussed (https://defence24.pl/sily-zbrojne/ukraina-2022-powrot-do-passchendaele-czy-pierwsza-wojna-ery-informacyjnej-czi-opinia). The fighting in Ukraine full demonstrates that despite the emergence of examples of a fresh approach to the application of the aforementioned rule and concentration of capacities, we proceed to observe the classical pursuit of concentration of resources, as demonstrated by the fresh fighting in the area of Bakhmut.
