Shen Hongyang’s decision to not pursue Su Dongming and Luo Tianyi who had abandoned their posts created a dip in morale and fighting spirit amongst the rest of the army. Based on the situation, if Shen Hongyang had deployed the 7 assault helicopters to give chase, Luo Tianyi and Su Dongming did not possess any anti-air defence, and thus would be defeated, slowing their retreat down. The rest of the army could then work together to capture the 2 of them and their troops to act as cannon fodder to slow the zombie horde down. That would have been the best course of action to take.
