Nigeria Has The Largest Military Service Population in Africa

Out of the whole of the African continent, Nigeria stands as the most populous nation by far, and this translates to military might. With more than 90 million Nigerians fit for military service, this country dominates its regional rivals in this aspect. Although Nigeria might not have the technological advantages of other African militaries like Egypt or Algeria, it makes up for it in sheer manpower. Here, 24/7 Wall St. is exploring African militaries and which ones have the largest populations that are fit for military service.

To determine the African countries with the most people that are fit for military service, 24/7 Wall St. reviewed the 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 ranked these countries based on their fit-for-service population. We also included supplemental information regarding active military personnel, reserves, paramilitary forces and total military personnel as well as each country's overall strength score and defense budget.

Here is a look at the countries with the most people that are fit for military service in Africa:
