Military

Military forces (often called the military when specific to a certain group) are a group or groups of people that are given power to defend a country or territory with weapons. They are armed, so they are called the armed forces. The military protects its country by defending it from the armed forces of enemies, if there is a war. The military can also be ordered by the government of the country to attack another country. The word "military" comes from Latin miles, warrior.

There are many jobs people do in a military. Some jobs are for fighting and some are for other work to support the military. Some things people do in the military include the use of weapons,driving and operating vehicles,and repairing weapons. Other people in the military learn how to fly specialized aircraft, be a pilot on ships, or repair machines. People in the military usually wear clothes called a uniform. In some places, especially where there may be combat, a uniform often has a camouflage pattern which is designed to make the person hard to see in the forest or desert.

There are two ways to join the military. In many countries, people join the military because they want to. In other countries, there are laws that say some people have to be in the military, even if they do not want to be. This is called the draft or conscription. It usually depends on age and physical fitness. Old military people or former military people are called "veterans". Some are members of a military reserve force.

The military of a country has different branches or organizations which do different kinds of work. Usually they include:

• Army (land) – A military force of soldiers who operate mainly on land or in land vehicles such as tanks. They also use helicopters.
• Navy (sea) – A military force that uses ships and boats. Some navies have planes. People in a navy are called sailors.
• Air force (air) – A military force that uses mainly aircraft.

Many countries include other branches:

• Gendarmerie – A military force that exists for police and security work. It operates mainly inside its own country.
• Marines – Military force that serves on ships, but are also trained to fight on land when needed. Their main job is to attack by landing on enemy beaches. They work closely with a navy, but are not sailors. They may also have their own boats, planes, and helicopters.
• Space force (space) – A military force that uses spacecraft, including satellites.
• Air defense force – Usually part of the army, but sometimes part of the air force or independent.
• Strategic rocket force – May be part of the air force or the army, or independent.

Some countries even have small units which perform special actions which are difficult. They are called special forces.

There are also mercenaries, soldiers who fight just for pay and have little loyalty to whomever might hire them, and private military contractors (PMC), which are under the command of a company (civilian company). The Medieval Italian condottieri were a historical example of PMCs. A warlord may have a private army, which are often no more trustworthy than common gangsters or criminals.
