I Am A Special Ops Soldier 2: Knives Out (2012)

During the 1980s, He Weidong, a sniper of the PLA Special Operations Forces, was killed by a foreign mercenary code-named "Scorpion" when saving his spotter, Fan Tianlei. Fifteen years passed, He Weidong's only son, He Chenguang, has grown to become a national martial arts champion and was about to attend an elite sports university. However, his plan was interrupted by the sudden appearance of Fan Tianlei, now an instructor of the Special Operation Forces. Fan Tianlei convinced He Chenguang to join the army instead of attending college, along with a rebellious young man, Wang Yanbing, and a persevering rural youth, Li Er'niu. Fan Tianlei sees a better future for them in the army than in their current occupations. They are assigned to the same squad, and all demonstrate superior talents. The PLA is forming a Special Operations Squad called "Red Blood Cell," and they are nominated and pass the strict selection process. The "Red Blood Cell" Special Operations Squad faces various arduous tasks and matures from ceaseless battles against drug traffickers, professional killers, and other outlaws. In a rescue mission on the open seas, they meet "Scorpion" again, and He Chenguang strikes him down, finally revenging his father.
