Why do Korean boys have to go to the army at the age of 21?

Because South Korea is very small, in order to prevent the invasion of other countries, all South Korean men before the age of 30 have to go to the army to fulfill their national defense obligations and defend the country.

The country is relatively small, and many people have to come to serve as soldiers.

The military service system is different in each country, and the conscription system, the number of conscripts is changed, increased or decreased according to the military needs of the country in that year. Obviously, South Korea's conscription system is different from China's conscription system, which is voluntary enlistment, but South Korea implements a strong and systematic military service system, that is, every young man of school age must enlist in the army.

This military service system is practiced for the following reasons:

South Korea is a small country, so there are even fewer young people who can serve as soldiers to defend the country. Therefore, South Korea needs a large number of young people who are willing to serve as soldiers and defend their families and the country. However, being a soldier is very hard and tiring, and requires a lot of training every day, and some young people are reluctant to join the army, or their families are reluctant to let him become a soldier.

Therefore, in order to prevent this situation, South Korea has implemented compulsory military service to avoid the situation that no one wants to be a soldier when recruiting.

After all, South Korea is an effect, and it will be weaker than other military powers in all aspects of the military, and South Korea has been in confrontation with North Korea before, and in order to prevent North Korea from suddenly launching an attack on South Korea, South Korea has to make military preparations. Therefore, South Korea implements such a strict conscription system in order to prevent problems before they occur and to defend their country. After all, every country will understand the truth that a weak country has no diplomacy, and it is very important to judge whether a country is a weak country, and the country's military strength is very important.

Everyone who is willing to be a soldier and defend his family and country is a hero, sacrificing his time with his family and friends in exchange for the happy life of others.

Yes, every Korean man must go for a medical examination when he reaches the age to see if he meets the standards. Soldiering is a stage of life that Korean boys have to go through because of their small population.

Well, yes, in South Korea, men are required to serve in the military until a certain age.

As for the type of troops, it depends on the health of the body.

Disability or physical condition.

Exemption from military service may be granted on a case-by-case basis.

Artists can apply for a deferment of military service.

South Korean law requires men between the ages of 20 and 30 to serve for at least two years. Because there are a total of 50 million people in South Korea, half of them are women, 25 million people. According to the age structure of the Korean population, there are about 1.8 million people between the ages of 20 and 24 plus about 1.6 million people between the ages of 25 and 29, that is, three or four million people.

Because everyone served for two years, there were five batches of military service in the decade between the ages of 20 and 29, and 3 million divided by 5 equaled 600,000 4 million divided by 5 equaled 800,000. South Korea's current military strength is 680,000. So you look at a turnip, a pit.

Only two years of national service can guarantee that the country will have enough troops every year.

My data is approximate and not precise enough, but it already speaks for itself. You ask me why South Korea has to maintain such a huge army of 680,000? Because North Korea has 1.2 million troops, and North Korea has 10 years of military service.

The reason why North Korea has more soldiers than South Korea is because a large number of North Korean women also serve in the military.

Why does China not need all the people to serve in the military, because there are 1.4 billion people in China, 700 million men, and 130 million people between the ages of 20 and 29, so there is no shortage of soldiers of appropriate age in our country, and many people can't become soldiers if they want to.

Conscripts, every citizen's duty, we are too many, there are plenty of soldiers.

South Korea's population is too small, only about 50 million (Japan has a population of about 120 million, the United States has about 600 million), its geographical location is in the Asia-Pacific region, where the atmosphere is relatively tense, and it is still in a period of confrontation with North Korea, so the demand for military strength is large, so in order to ensure that the number of troops is sufficient in case of war, the compulsory military system is implemented.

Secondly, in the event that the war lasts for a long time and there are not enough active troops, there can also be a compulsory conscription of adult men who have served in the military throughout the country, that is, "all the people are soldiers".

The situation is quite different in China, with 2.2 million active troops (after several disarmaments) and a large number of reservists and veterans. The army was completely sufficient, so the conscription system was adopted.

South Korea's military service system states:

Male citizens between the ages of 20 and 30 are required to serve in the military, and the duration of service varies depending on the branch of the military, but the shortest branch of the military is also required to serve for 24 months. Korean boys who do not go to university after graduating from high school will be notified of their enlistment. If you go to college, you usually take a leave of absence in your sophomore year and go to serve in the army for two years, and then come back to continue your studies.

There are also people who choose to go to graduate school after graduation, but they must also serve after completing graduate school. Only those who have serious illnesses or who have made a great contribution to the country may be exempted from military service.

Our country has a large population, and when you reach the age, you only need to register for military service, and there are many people who want to be a soldier but can't become a soldier, so you can't feel whether you want to serve in the military or not.

Because South Korea has a compulsory conscription system.

Grades 1 to 3 are qualified candidates for active duty, and they are respectively assigned to the army, navy and air force on active duty.

Level 4 refers to those who fail to meet the standards of some projects, and will be dispatched to national and local ** institutions or public organizations as "public welfare service officials".

Level 5 personnel are to be assigned to Second Civil Service and are only dispatched in case of emergency.

Level 6 is a person with a serious illness or mental disorder who is exempt from military service.

Level 7 is considered to be unable to determine the physical condition and must be re-examined the following year. The length of service varies slightly from branch to branch, with the general length of service being 21 months.

South Korea has no wartime command, so why should men have to serve in the military when they reach adulthood? The reason is simple.

Yes. From the age of 16, it can be delayed for 5 years.

All men in South Korea are required to serve in the military. There are two types of military service in South Korea: regular service (24-28 months) and reserve service (28-32 months).

Ordinary people serve in regular service, and special people serve in reserves. Special people include: physical and mental defects; Those who have special academic achievements; special family circumstances; Those who have special skills in a special industry.

Yes, in South Korea, it is stipulated that men must serve in the military until a certain age, and as for what type of service, it must be determined according to their physical health.

Disability or physical condition.

Exemption from military service may be granted on a case-by-case basis.

Artists can apply for a deferment of military service.

Not all, except in special circumstances.

3.There is no financial ** at home.

Yes, as with Wanwan, military service is mandatory.
