As of May 2025, China had the largest armed forces in the world by active duty military personnel, with about *********** active soldiers. India, the United States, North Korea, and Russia rounded out the top five largest armies. Difference between active and reserve personnel Active personnel, also known as active duty in the United States and active service in the United Kingdom, are those individuals whose full-time occupation is being part of a military force. Active duty contrasts with a military’s reserve force, which are individuals who have both a military role and a civilian career. The number of active duty forces in the U.S. is much larger than its reserve membership. What is the strongest army? The strength of a country’s armed forces is not only determined by how many personnel they maintain, but also the number and quality of their military equipment. For example, looking only at personnel does not factor in the overwhelmingly higher number of nuclear warheads owned by Russia and the United States compared to other countries. One way to answer this question is to look at the total amount of money each country spends on their military, as spending includes both personnel and technology. In terms of countries with the highest military spending, the United States leads the world with an annual budget almost ***** times larger than second-placed China.

In 2025, the United States had the largest number of active military personnel out of all North Atlantic Treaty Organization (NATO) countries, with almost *** million troops. The country with the second-largest number of military personnel was Türkiye, at around ******* active personnel. Additionally, the U.S. has by far the most armored vehicles in NATO, as well as the largest Navy and Air Force. NATO in brief NATO, which was formed in 1949, is the most powerful military alliance in the world. At its formation, NATO began with 12 member countries, which by 2024 had increased to 32. NATO was originally formed to deter Soviet expansion into Europe, with member countries expected to come to each other’s defense in case of an attack. Member countries are also obliged to commit to spending two percent of their respective GDPs on defense, although many states have recently fallen far short of this target. NATO in the contemporary world Some questioned the purpose of NATO after the fall of the Berlin Wall in 1989 and the collapse of the Soviet Union a few years later. In 2019, French President Emmanuel Macron even called the organization 'brain-dead' amid dissatisfaction with the leadership of the U.S. President at the time, Donald Trump. NATO has, however, seen a revival after Russia's invasion of Ukraine in February 2022. Following the invasion, Sweden and Finland both abandoned decades of military neutrality and applied to join the alliance, with Finland joining in 2023 and Sweden in 2024.

Context

I've created this dataset as I want to compare the Russia and the NATO's armies.

Content

You will find a ranking with a Power Index calculated for every country by the "Global Fire Power" organization : this is not simple to make a fair comparison between Russia and the 27 countries of the NATO because we can't really summarize what "would be" the Power Index of an alliance.

Like it or hate it, military power is always become one crucial aspect in world's diplomacy. Those who have more personnel or sophisticated weapons are easier to get what they want. And those who don't can find another way to ensure their sovereignty intact but their needs also fulfilled. And we must admit that flexing military power always be a thing for countries in the world. That's why I collected military personnel data from about 126 countries in this world in 25 years range.

Content

What inside this dataset are not only numbers. It also told us the stories about why the numbers goes up and down. We can see the dynamics of the amount of military personnel each countries have per years. Some multiplied, some depleted and unable to regain back.

Not all countries data are in this dataset. I only collect data from countries where military data is available for each year. There are problems with Angola in my dataset, since they are all Null. I'll try to fix it later.

The United States led the ranking of the countries with the highest military spending in 2024, with 997 billion U.S. dollars dedicated to the military. That constituted almost 40 percent of the total military spending worldwide that year, which amounted to 2.7 trillion U.S. dollars. This amounted to 3.4 percent of the U.S.'s gross domestic product (GDP), placing the country lower in the ranking of military expenditure as a percentage of GDP, compared to Ukraine, Israel, Algeria, Saudi Arabia, and Russia. China was the second largest military spender, with an estimated 314 billion U.S. dollars spent, with Russia following in third. Defense budgetAccording to the U.S. Congressional Budget Office, the outlays for defense will rise to 1.1 trillion U.S. dollars by 2033. The largest parts of the budget are dedicated to the Departments of the Navy and the Air Force. The budget for the U.S. Air Force for 2024 was nearly 260 billion U.S. dollars.Global military spendingThe value of military spending globally has grown steadily in the past years and reached 2.7 trillion U.S. dollars in 2024. Reasons for this are the outbreak of the Russia-Ukraine war in 2022, the war in Gaza, as well as increasing tensions in the South China Sea. North America is by far the leading region worldwide in terms of expenditure on the military.

The average for 2022 based on 145 countries was 1.98 percent. The highest value was in Ukraine: 33.55 percent and the lowest value was in Haiti: 0.07 percent. The indicator is available from 1960 to 2022. Below is a chart for all countries where data are available.
