They are doing thing Russian style... a disorganized, couldn't-care-less attitude with some loose ends but still getting the job done...
They would have three times the lost because of that.
The analysis of the use of aerospace power by Western analysts has a Western interpretive bias on the VKS's view of employment, this is called ethnocentrism - they appreciated the other in the light of our own reality.
Russian air doctrine is not yet consolidated. This is a fact and there was no doctrinal adherence of Russian air power to Western models, until today VKS fights for the independence of air power against the Army's land force, as if it were a ground attack force and rotary wings to support the forces ground forces, an air force subordinate to the Army.
The PVO (Soviet Air Defense Force) and VVS (Soviet Air Force) were consolidated into the VKS only in 2015 and were ineffective in what Douhet called the air domain.
But not always air supremacy or air superiority is the degree of air control desired or planned by an air force, in Brazil we have the classification of "favourable air situation", the minimum degree of air control or air dominance is expressed in a geographic space in an undetermined period of time, the RuAF still follows the discussion of the air precept of the original theorists who aimed at an independent air force, perhaps there is air power as a weapon to support surface operations.
Ukrainian air bases have been attacked with ballistic and cruise missiles from ships and land systems in a greater share than air-launched missiles, strategic bombers are also being sparsely employed and the difficulty of the RuAF to conduct complex air operations, operations that involve more than one type of aircraft in more than one type of mission trying to integrate a common purpose as a "Strike package".
When all this is understood, analysts will know how to analyze the Russian air force.
