An assessment of the enemy's intelligence, based on the number and types of weapons the enemy believes Russia has. Of course, real numbers are classified information, so it is impossible (and not necessary) to verify the enemy's information. But even relying on such data, it is possible, for example, to soberly assess the potential of the available means for solving certain problems. But it is the calculus of war that largely determines when it comes to the "desires" of those who want to win easily and simply by pressing the magic button "kill all enemies" or "destroy all bridges". The harsh reality of production capabilities clearly shows the amount of funds that can be applied over a period of time. Especially considering the coefficients of the number of misses, the percentage of interceptions, the percentage of failures - and they significantly reduce the number of available weapons, and it is always less noticeable than the number produced. Therefore, when looking for simple and understandable answers (solutions/suggestions), it is useful to adjust and coordinate them with reality so as not to reach wrong conclusions. Which, of course, are extremely popular with the average person, but have nothing to do with the real situation. Russian engineer.
