• 妈妈妈的原版汉化优化by 76561198406508408本MOD已对数据标注MOD完成了兼容 已基本完成对电力系统的翻译 原版的翻译有很多歧义甚至错误，如“牵引火炮”包含防空炮、反坦克炮、火炮和火箭炮但不包含支援连，而“牵引火炮及轻型火炮”反而包含的内容比前者少了防空炮和反坦克炮，但是包含支援连。这是一个巨大的错误，正确的翻译应该是前者为“所有火炮营(除支援连)”，后者为"所有火炮(除防空炮及反坦克炮)"。 因此，本MOD对一些内容进行了更加精确的翻译，以消除歧义 本MOD基本由作者一人完成，不一定能及时发现问题，希望能得到更多反馈18.4k downloadsupdated 28 d ago
