The GFP list makes use of over 50 factors to determine each nation's Power Index ("PwrIndx") score. This provides the final ranking and allows smaller, technologically-advanced, nations to compete with larger, lesser-developed ones. Some bonuses (and penalties) are added for refinement. In the end, we hope it presents an unbiased outlook on the potential conventional military strength of a given country if only to stir some healthy debate.
Things to keep in mind:
• Nuclear capability is NOT taken into account
• Geographical factors influence every final GFP ranking
• Ranking does not solely rely on total number of weapons available
• Natural resource reliance (use/production) is taken into account
• Land-locked nations are NOT penalized for lack of a standing navy
• Naval powers ARE penalized for limited naval capabilities
• Current economic health for each country is taken into account
• Current political/military leadership is NOT taken into account
As of 08/15/2015 there are a total of (126) countries included in the GFP database.
