KYIV, UKRAINE - JANUARY 22: Civilian participants in a Kyiv Territorial Defence unit train on a Saturday in a forest on January 22, 2022 in Kyiv, Ukraine. Across Ukraine thousands of civilians are participating in such groups to receive basic combat training and in time of war would be under direct command of the Ukrainian military. While Ukrainian officials have acknowledged the country has little chance to fend off a full Russian invasion, Russian occupation troops would likely face a deep-rooted, decentralised and prolonged insurgency.

Many countries on a global scale rely on reservists for support. Should a conflict erupt, these countries already have a reserve of military personnel ready to jump in. Although these military members are not on active duty, they are a crucial and central component of any military force.

To identify the countries with the most military reserve personnel, 24/7 Wall St. reviewed the 2024 Military Strength Ranking from Global Firepower, an annually updated defense-related statistics website with information on 145 countries. Countries were ranked on the total number of military reserves. We included supplemental information regarding active personnel, total population, fit-for-service, paramilitary forces, and overall military strength score.

A country’s military reserve forces say a lot about its defense strategies, capabilities, and readiness. Reserves are a great way to maintain military strength without breaking the bank on a standing army. Looking at which countries have the most military reserve personnel provides a greater look into how that country views its defense standing and what threats it worries about.

Here is a look at the countries with the most military reserve personnel.
