South American Powers Ranked by Military Strength

South America has continued to see growing military forces and the shifting of power to a select few.

The GFP list makes use of over 50 factors in our in-house formula to determine a given nation's Power Index ('PwrIndx') score. This provides the final ranking while also allowing smaller, more technologically-advanced, nations to compete with larger, lesser-developed ones. Some bonuses and penalties are added for refinement that, in the end, we hope presents an unbiased look into the potential conventional military strength of a world power.

For 2018 there are a total of 11 countries included in this listing.
