Using over 55 factors to determine a country’s PowerIndex score, the Global Firepower 2018 list ranks the most powerful military nations in the world. Of the 136 advanced and lesser developed nations included, the parameters include their geographical location, natural resource reliance, manpower and current economic health. It must be noted that nuclear capability and current political/military leadership is not taken into account. Also, land-locked nations are not penalized for not having a standing navy. Here's a look at the 50 most powerful military nations, according to the list, as of April 14, 2018.
