Here is one bit from an excellent longer piece by Michael Kofman:
Russia’s gradual approach is inherently vulnerable, since it is based around fielding the bare minimum amount number of troops in the battlespace to achieve desired political ends. In order to deter and dissuade peer adversaries Russia will often introduce high-end conventional capabilities, such as long range air defense, anti-ship missiles, and conventional ballistic missile systems. These weapons are not meant for the actual fight. Instead, they are intended to make an impression on the United States. The first goal of the Russian leadership is to make the combat zone its own sandbox, sharply reducing the options for peer adversaries to intervene via direct means. America does this in its campaigns by attaining air superiority. Russia’s method is cheaper: area denial from the ground.
…Beyond its political objectives, Russia places strong emphasis on having an exit strategy. In fact, a viable exit strategy seems just as important than whatever they are trying to achieve. It is perhaps one key point where Russia’s leaders would agree with Weinberger and Colin Powell. But unlike the United States, they actually practice it.
