To determine the countries with the strongest military might, 24/7 Wall St. reviewed data from Global Firepower, a part of the Military Factory network of sites. Countries were ranked based on the GFP’s 2022 Military Strength PowerIndex, a composite of over 50 factors measuring such categories as military might, financials, logistical capability, and geography.
The smaller the PowerIndex value the more powerful a nation’s theoretical fighting capability is — by conventional means as nuclear weapons were not taken into account. (Though a perfect PowerIndex score is 0.0, such a score is currently unattainable given the scope of the study, Global Firepower explains.)
Data on armed forces personnel and armed forces personnel as a percentage of the labor force came from the International Institute for Strategic Studies, which used World Bank data, and is for 2019. Data on the number of active military aircraft came from FlightGlobal and is for 2021. Data on military expenditure in 2020 came from the Stockholm International Peace Research Institute.
