Ironic seeing the human wave of Ukrainians sent into the land mines and open fields to be hit by indirect fire. Russia has no problems supplying this war of attrition and it could be argued that they sought to impose such a war after pivoting from the maneuver based doctrine of the start of the SMO. As I quoted in the rail line the Russian supply chain is limited by the rail and as such would be unable to sustain themselves far from the lines as opposed to the established and new lines they have created to the Donbass region.

"The capacity to detect and strike targets at ever-greater distances and with ever-growing precision increases the vulnerability of dense troop concentrations, and therefore limits the ability to conduct large-scale sequenced and concentrated operations. As such, in order to enhance survivability, current battlefield conditions are forcing military units to disperse into smaller formations, dig in, or both, unless these conditions are effectively countered. As a result, the battlefield tends to become more fragmented, offering more independent action to lower tactical formations as the depth of the front is expanding to a considerable extent."

"As a survey of decades of history illustrates, Russian military strategy over the past decades has correctly forecasted a number of implications of advancements in weapons, as well as sensor technologies, that are currently affecting the character of warfare in Ukraine."

"The operational level of war sits between tactics, which consists of organizing and employing fighting forces on or near the battlefield, and strategy, which involves aspects of long-term and high-level theatre operations, and the government's leadership. The Soviet Union was the first country to officially distinguish this third level of military thinking, when it was introduced as part of the deep operation military theory that its armed forces developed during the 1920s and 1930s and utilized during the Second World War."

"After the failure of the initial invasion, the subsequent period of the fighting in the Donbas was at first marked by Russian dominance in fires. Besides precision munitions, the employment of UAVs for target detection greatly enhanced the effectiveness of Russia’s large numbers of legacy artillery systems. Russian artillery batteries employing UAVs for target detection generally showed themselves capable of engaging Ukrainian positions within minutes after being detected. As a result, Ukrainian infantry companies were forced to disperse and often occupied front lines up to three kilometers wide. Consequently, battalions covered frontages that are traditionally the responsibility of brigades. Russian artillery superiority and sensor density even prevented Ukrainians from concentrating in units above company size, because anything larger would be detected prematurely and effectively targeted from a distance."

"Russian forces also rarely employ armor and infantry in concentrated assaults and in the defense occupy dispersed positions, while increasingly drawing on artillery to blunt Ukrainian attacks."

"However, current battlefield conditions are adding the related difficulty of achieving the concentration of forces necessary for establishing main efforts during offensive operations. This is reducing large-scale engagements and thereby necessitating a concentration and synchronization of effects, rather than a traditional physical massing of troops. In turn, this places an extra burden on command and control, especially when contested by electronic warfare. Only by disrupting the opponent’s kill chain can larger formations regain the ability to concentrate and engage in maneuver warfare. During the war in Ukraine, superiority in kill-chain effectiveness has become one of the prime objectives for both sides. In this war and any other characterized by the same dynamics, this superiority becomes an essential condition for victory."
