List of countries by size of armed forces - Wikipedia, the free encyclopedia
That's a pretty interesting comparison by numbers of worldwide armed forces. I'm no expert on military and do not aspire to be, so I can't really comment on what the numbers mean in the end, but at first glance the US seems very competitive to say the least.
Aircraft carriers are said to be pretty much the strongest unit there is (next only to nukes that due to practical reasons don't really are of much use other than deterrent) - I bet a US aircraft carrier could probably take most of the countries on this planet by itself -, and the US has far more than any other country and almost more than the rest of the world together.
