Ren Xiaosu's cooperation with P5092 was to have Ren Xiaosu voice his ideas for P5092 to follow.
This was what P5092 had suggested. In other words, the entire 3rd Division infantry brigade of the Pyro Company had become Ren Xiaosu's reinforcements. These few thousand soldiers were only here to provide him with tactical support.
Since Ren Xiaosu ordered them to circle around from A17 to A21 to carry out an ambush and suppress the enemy, the infantry brigade would just have to follow their orders and provide tactical support.
For P5092, this was the best battle plan he had chosen after giving it rational consideration.
An absolutely outstanding commander definitely did not have to take the lead at all times. As long as he could win, he was allowed to achieve it through any method.
