Over the past year, countries around the world have risen and fallen in terms of military power. One of the most pivotal factors in this calculus is the overall size of a country’s military. While some countries might have technologically advanced forces, they might not have the manpower to back them up. Here, 24/7 Wall St. is taking a closer look at military powers with the largest armies and fit-for-service populations.

To determine the countries with the largest military forces, 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. We ranked these countries according to their fit-for-service populations, but included numerous military personnel metrics for each country. The smaller the PowerIndex value the more powerful a nation’s theoretical conventional fighting capability is.

This is an updated version of a previously published article, now including more recent 2025 Military Strength Rankings along with various other military personnel statistics.
