I have modified some of the Soviet army's offensive logic and route. You can try Task 2 first. There should not be a large number of entities piled up on the front line now, and the number of enemies participating in the battle will remain within a fixed range. If you don't have time to eliminate waves of enemies, the next wave won't keep surging forward. The defensive firepower is more evenly distributed. It is recommended to use green supply boxes to supply artillery shells. At present, the plot ends with the cessation of the southern offensive.
