A government-authorized, government-funded, and government-maintained combat force is what we mean when we say military.
The military is mainly a fighting force, but it may also conduct humanitarian services, such as distributing food, water, and medical attention to needy individuals. The military is primarily utilized for national defense in most developed nations (and humanitarian work).
A country’s military may play an aggressive role, as the wars of World War I, World War II, and the Russian invasion of Ukraine in 2022 indicate.
In the eyes of many, large armies display strength, and they can instill confidence in people and allies alike. The military budget of the United States is the highest in the world.
Contrary to popular belief, many nations do not maintain any kind of organized military forces, no matter how important they consider them to be. Countries without armed forces usually fall into one of the following three groups:
- Military demilitarized countries.
- Military-free countries were founded by their founders.
- Ex-colonies/dependencies still under the protection of the countries they were formerly part of having a military. Because it was formerly a French colony, Monaco currently receives its defense from the country that once colonized it.

Military-Free Countries and Territories
In the CIA World Factbook, there are 39 nations and territories where the government does not have any kind of military. De facto militaries exist in various countries, despite the lack of a regular military force per the CIA’s definition.
