The world as we know it has largely been shaped by competing militaries maintaining the balance of power and the current world order. These nations hold significant sway over international relations with their advanced weaponry and extensive manpower. Here, 24/7 Wall St. is exploring the most powerful military forces in the world.
To determine the countries with the strongest military might in the world, 24/7 Wall St. reviewed 2025 Military Strength Ranking from Global Firepower, an annually updated defense-related statistics website with information on 145 countries. Global Firepower ranked 145 countries based on their PowerIndex, a composite of over 60 measures in categories such as military might, financials, logistical capability, and geography. The smaller the PowerIndex value the more powerful a nation’s theoretical conventional fighting capability is. We included supplemental information regarding active military personnel, aircraft, vehicles, and naval power as well.
Here is a look at the strongest military powers in the world:
