要获得战斗经验，你必须去战斗。就是这么简单。虽然你可以努力使训练尽可能逼近真实，不过不可能完全重现战斗带来的混乱和内心反应。首先我肯定要提一下三巨头：中国、美国和俄罗斯。
然而，这三国的军力强大是无需赘言的，因此我要再说说另一个国家。
United Kingdom
英国
The UK’s one of the few non-American countries that actually have aircraft carriers which is a pretty big deal. Plus they have an active military presence in several countries. The UK’s also one of the 5 recognized nuclear powers having around 160 nukes and 4 nuke submarines.
