Across Europe, the military reserve forces vary to a large degree. This reflects a number of diverse national security strategies that have arisen from different historical contexts. However, the largest reserve forces come from some of the biggest contributors to NATO. Here, 24/7 Wall St. is taking a closer look at these European reserve forces with a focus on the NATO members in particular.
To identify the European countries with the largest military reserve forces, 24/7 Wall St. reviewed 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 reserve personnel. We included supplemental information regarding total personnel, active personnel, total population, fit-for-service, and overall military strength score. Countries without a reserve force were excluded.
Here is a look at the largest reserve forces in Europe:
Why Are We Covering This?
Understanding the military dynamics in Europe is important considering the continent’s deeply rooted geopolitical challenges going forward. Historically, Europe has been marked by wars, shifting alliances, and territorial disputes, and yet it still remains a key player on the global stage. At the same time, alliances like the EU or NATO are some of the most powerful in terms of their influence on the world. Whether it is a question of NATO’s expansion or Russia’s campaign in Eastern Europe, these military forces tilt the region’s balance of power.
