In addition, the guard plate can also comb the airflow passing through the chassis, thus improving the handling performance.

讲述了抗日时期，几个身世坎坷、身份各异的青年走上热血革命道路的传奇故事。该剧是“前进”原班人马打造的一部更加新颖的战争大戏。嘎子、大招，相依为命的两位亲兄弟，一个憨一个傻，分明就是一对活宝。弟弟嘎子性格冲动，常常好心办成坏事；哥哥大招有智力缺陷，却往往能弄巧成拙。日本侵略者血洗揦子村时，全体村民为掩护嘎子和大招，被残忍杀害。仓皇逃难的二人巧遇外甥“狗蛋”——八路军营长赵有亮。誓言为乡亲们报仇的兄弟俩，一心想加入八路军，却遭到赵有亮的拒绝。为了证明自己有能力成为合格的八路军战士，嘎子和大招抓到为寻找妹妹而逃脱国民军的猴子作为“投名状”。最终，他们各自在硝烟战火中历练、成长。该剧希望通过最为真实感的人物塑造以及写实的战争场景，为荧屏增添一段可以长久回味的红色题材好故事。
