What are the commonweal soldiers and active servicemen currently serving in Korea? Do they have the right to choose the type of service they want?

The commonweal soldier I know is Kim HeeChul from SJ. Military service is divided into five grades. The military will let you do military service according to the results of everyone's physical examination, not just which one you want to go to. Generally, they are second-class active servicemen.

Level 5 is already a person who has had a serious illness but can live independently. Short-term military theory training.

Level 4 health, you can try simple military training 1 year.

Level 3, 22 months, physically injured but recovered well, and can perform military tasks.

The second level is 26 months, which is basic active service.

1 grade is 3 years, in excellent health, engaged in related industries, generally the air force and navy.
