 Their task is simply to go to our positions, causing us to fire on them. The Russians use these units to see where our firing equipment is located and to constantly exhaust our units. Our guys stand in positions and fight, and when four or five waves of the enemy come at you in a day, which you have to destroy without end, it is very difficult not only physically, but also psychologically. The tactic is a sign of Russia making the most of its key advantage – numbers.
