Having a formidable standing army is important when considering the overall military strength of a nation. However, the ancillary forces like reserves and paramilitary further add to the strength and scale of any given country’s military force. The total personnel within a country’s military gives a fuller picture to this, especially considering protracted conflicts or long-standing tensions with other nations. Here, 24/7 Wall St. is taking a closer look at the countries with the most total military personnel in the world. (These are the world’s 30 strongest military powers – which nations are gaining on America?)

To determine the countries with the largest total military forces in the world, 24/7 Wall St. reviewed 2024 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 ranked these countries according to their total military personnel. We included supplemental information regarding active military personnel, military aircraft, and vehicles.

Here is a look at the countries with the largest militaries in the world:
