The combined infantry force move into the forest but are delayed by multiple traps set by Tom Cat and pinned down by sniper fire until Leng Feng manages to kill the shooter. Subsequently, the PLA and the Wolf Warriors are tasked with hunting down Tom Cat‘s squad to restore their honor. During the exercise, Tom Cat and his mercenaries ambush a Wolf Warrior squad, killing one of Leng Feng's comrades. The Wolf Warriors participate in a training exercise in a remote and uninhabited forested region on China's southern border. Meanwhile, in the Philippines, crime lord Min Deng ( 敏登), the older brother of Wu Ji, hired ex-US Navy SEAL “Tom Cat” ( Scott Adkins) and his group to assassinate Leng Feng and avenge his brother. Long Xiaoyun offers Leng Feng a place in the Wolf Warriors. Leng Feng is sent to solitary confinement as punishment, but is approached by Long Xiaoyun ( 龙小云), the female commander of the legendary 'Wolf Warriors', an elite unit within the PLA tasked with simulating foreign tactics for the PLA to train against. Leng Feng ( 冷锋), a skilled PLA sniper, ignores orders to stand down and fires three shots at a weak section of the wall, penetrating through on the third shot and killing Wu Ji.
