The Iron Division is a well-known vanguard force in the G Military Region of our army. They are currently conducting a live-troop validation exercise at Eagle Mountain. This exercise is different from previous ones as there's no pre-set plan, but instead completely simulates actual combat. The Iron Division has suffered greatly in this unequal live-troop validation exercise. Commander Chen Haitao made a fatal mistake, and due to his health condition, the military region decided to transfer him to a militia division. His position as commander of the Iron Division will be taken over by Long Hansheng, the deputy leader of the guidance group for this exercise and a returned graduate from Russia.
Since Long Hansheng arrived at the Iron Division, the mid-level officers of the unit have resisted him due to their nostalgia for the old commander and the shadow of their defeat at Eagle Mountain. When news of the China-Russia joint military exercise reached the G Military Region, it was finally determined that the G Military Region would undertake this task. All units in the army were excited and hoped to gain this rare opportunity to conduct a joint exercise with foreign forces.
