精忠报国，浩气长存
“国家”这个词在整个中华民族的字典中，永远都是一个崇高的字眼。我们这个伟大的国就像一艘加足马力的航母，正向共产主义的目标昂首前行。而在其中，农民为国家这艘航母提供粮食，工人为她提供源源不断的动力，科学家为她的远行精确导航，文化工作者把她装点得雄伟壮观.可以说，每一个平凡的中华儿女都在以自己特有的方式报效国家，正如德国诗人歌德所说：“我们为祖国服务，每个人都按照资质，各习所能。”正是这些平凡人们的努力，铸就了民族几千年来的精神主流：精忠报国！而军人，就是她的铠甲，为她劈波斩浪；就是她的船骨，维系她的稳定团结；就是她的护卫舰，保卫她的安全！
“献身国防现代化的模范干部”苏宁曾说：“三百六十行，唯有军人是用鲜血和生命为祖国服务的，我热爱这一行！”军人，是报效国家最直接的职业，也是奏响精忠报国时代旋律的最强劲者。中国革命的伟大先行者孙中山先生曾说：“盖世捍族卫民者，军人之天职。”军队就是国家的坚强柱石，军人因报效国家而光荣！军人以“荣必天下荣，耻必天下耻”的爱国情感和职业自尊心，把报效国家看成自己的神圣职责与最基本的价值准则，在中华民族历史上描绘出一幅幅最壮美的图画，谱写了一曲曲荡气回肠的英雄赞歌！
“天行健，君子以自强不息”，老祖宗教导了我们自立自强的民族精神；“风尘三尺剑，社稷一戎衣”更是体现了报效国家，为国为民的崇高情怀；苏武北海牧羊二十八载，宁愿自刎，绝不投降，托鸿雁
投书，以示高尚气节和对国家的忠诚；岳武穆背刻着“精忠报国”四个血字，“北逾沙漠，喋血虏廷”，为实现“还我河山”的报国之志，挥师北伐，英勇杀敌；林则徐“苟利国家生死以，岂因祸福避趋之”的责任感和使命感，又曾激起多少爱国志士前仆后继，报效国家；东北抗联八名女烈士面对敌军诱降，坚守气节，毅然投江，慷慨赴黄泉，以示报国之情。
自古言：覆巢之下，岂有完卵；皮之不存，毛将焉附；国之不国，家又何在。有一首诗这样写道：如果我们不去打仗，敌人会把我们杀死，指着我们的尸体说，看！这是奴隶！亿万中华热血儿女，谁受得了沦为亡国奴的奇耻大辱，谁能忍受另外一种颜色的旗帜在我们的国土上趾高气昂，谁忍心我们的姐妹遭到蹂躏，我们的兄弟遭到屠杀，我们的同胞被当做奴才！谁又忍心听那铁蹄践踏下祖国母亲发出的沉重叹息！我们不能！那就穿上军装，拿起武器，走向战场吧！用热血与生命去保卫祖国，报效国家！
如今，战争的硝烟虽已消散。但是对军人来说，只有战争时期和战争准备时期！战时时期，我们可以奔向战场，英勇杀敌，以身报国。那么和平时期的报效国家是什么呢？听，神仙湾上暴风雪的怒号在告诉我们答案，曾母暗沙击打礁石的浪潮在告诉我们答案，乌苏里江边清晨的鸟语在告诉我们答案！看，练兵场上的冲杀呐喊在告诉我们答案，实验室里不眠不休的攻关在告诉我们答案，教室里的刻苦专研同样在告诉我们答案！
军人在和平时期报效国家，是指
未来信息化条件下的战争，对当代军校学员提出了更高的要求。要求我们爱军习武，锤炼精兵，苦练杀敌本领；要求我们应该开阔视野，关注世界新军事变革的发展趋势；要求我们时刻警惕，居安思危，枕戈待旦，要求我们随时准备为国家利益而战斗！
同学们，军队生来为战争，军人生来为打赢！当今世界并不太平，战火并不遥远，我军履行新世纪新阶段历史使命的任务十分艰巨。戎装在身，报效国家，坚决捍卫国家主权和领土完整是每个军人义不容辞的责任，也是我们军人价值的根本所在。
同学们，为了祖国的一方蓝天，为了母亲宁静祥和的微笑，为了国家的繁荣昌盛。战斗吧！因为我们的名字是战士！
