China tops the ranking of the world's largest active military forces with more than two million personnel, according to new data from World Population Review. The UK, by contrast, ranks 35th with an estimated 141,100 active military personnel, underscoring a substantial gap in troop numbers compared to leading nations.
Global Military Size Rankings
India and the United States also feature near the top of the list, while countries including North Korea, Russia and Ukraine have hundreds of thousands of serving troops. The figures illustrate the difference in size between armed forces worldwide, although having more soldiers does not necessarily mean a country has a stronger military.
South Korea holds tenth place with around 500,000 active military personnel. Its relationship with North Korea helps explain the large force, as the two countries have been divided for decades and military service remains compulsory for most able-bodied South Korean men, many of whom spend around 18 months in the army.
Notable Forces in the Top Ten
Ethiopia sits just ahead of South Korea with 503,000 active personnel. Though not commonly associated with the world's largest armies, its armed forces are among the biggest in Africa, reflecting years of unrest including the conflict in Tigray and security operations beyond its borders.
Iran takes eighth place with around 610,000 serving personnel, comprising both its regular armed forces and the Islamic Revolutionary Guard Corps. The country has focused on developing missiles and drones amid ongoing Middle East tensions, drawing international attention to its weapons and regional influence.
Pakistan ranks seventh with 660,000 active military personnel. It borders Afghanistan, China and Iran, creating several security concerns, and is one of the countries in the ranking that possesses nuclear weapons.
