Let's continue to study history. In 2016-2017, large-scale anti-aircraft missile defense exercises begin, already at the unit level, not in sectors. At the same time, it is necessary to maintain the LBS and this complicates the work, in order to learn it is necessary to rotate, and if this can be done at the company level, then taking a battalion out of the line in many sectors is problematic. Today we know that the years of "war according to the Minsk rules" ended in a major combined arms operation and years of almost invisible work on the training grounds were not in vain.
