In a show of power on its 76th founding anniversary, China publicly presented over 30 active-duty warships on April 23, 2025. China has been ramping up its military spending in recent years as the nation seeks to increase its navy fleet. Today, China has the most naval vessels in the world and expects to expand to 425 ships by 2030. China is flexing its military might as tensions grow more intense between China and Taiwan.
The United States is known for having the most powerful military in the world. However, there are other military powers in the world with formidable forces as well. Also, when you rank countries based on the number of active military personnel, the U.S. does not come in first. That would go to China, with 2,035,000 active personnel. (Also see the countries with the most frigates in the world.)
24/7 Wall St. identified the countries with the most active military personnel by reviewing data from the 2025 Military Strength Ranking from Global Firepower, an annually updated defense-related statistics website with information on 145 countries. We ordered countries based on the total number of active military personnel, including information on personnel, reserves, total population, fit-for-service, as well as each country’s overall military strength score. The term “active-duty military personnel” refers to full-time service members in the armed forces. These are different than reserve forces or paramilitary forces that might be called into action should there be a deficit in full-time service members in times of war.

Why Are We Covering This Right Now?
China has been ramping up its military forces, which is especially critical considering tensions between China and Taiwan. Understanding global military dynamics is incredibly important due to the interconnected nature of international relations and conflicts. As long as civilization has existed, the world has witnessed shifting power balances and alliances that have ultimately shaped the current geopolitical landscape. Although key players like the United States, China, and Russia are considered the strongest military powers in the world, there are other nations with spheres of influence and strengths that impact global relations from a military perspective.
