Former Colonel Fernandez is appointed Minister of the National Anti-Drug Agency (SENAD) and purges the special forces to fight the first of many battles against drug trafficking on the border of Paraguay and Argentina.此外，为真实呈现影片中志愿军狙击战士二十岁出头的青涩形象，导演张艺谋大胆选用全新人演员阵容演绎狙击五班，除章宇饰演的班长刘文武、张译饰演的连长外，启用陈永胜、刘奕铁、黄炎、王梓屹、陈铭杨、王乃训、程泓鑫等年轻面孔，新人演员经历海选试镜选定，并在正式开拍前经历了严格的封闭式军事训练，从形象、姿态与气质上更加贴近真正的志愿军战士，主演陈永胜也曾在采访中深有感触真的像当了一次兵一样。
