The People's Republic of China has the biggest army, with more than 2 million military troops, compared to other countries. With 1.46 million and 1.39 million military troops respectively, India and the US are not far behind. Russia and North Korea both have sizable military forces, with 1.28 million and 900,000 soldiers, respectively.
Comparatively speaking, the armies of many nations are quite small, with some having less than 100,000 soldiers. For instance, South Africa and Argentina both have small armies, with 74,000 and 72,100 soldiers, respectively. Countries with even smaller armies include Slovakia, which has an army of only 17,950 soldiers.
It's important to remember that a country's military capability is not just determined by the size of its army. Other important elements include tactics, technology, and training. Additionally, some nations could rely on the navy or air force as well as other components of their armed forces to supply military capabilities. Overall, when it comes to military strength, a nation's army size is only one factor.
