What the Hell Is a Bloody Battle at Hacksaw Ridge When Someone Is in the Special Forces?

"How many enemies have you killed?" Chang An: "I haven't counted. I only know that I am still alive." "So how many high-risk missions have you carried out?" Chang An: "I don't want to copy the confidentiality regulations. I can only tell you this. I learned guns from John Wick and went on a rampage in the Continental Hotel. I struggled to survive in Hacksaw Ridge and saved a fallen black hawk..." All of the above start from the night when Chang An left the company.
