First of all, your rank after enlistment depends on the way you choose to enlist: if you choose to enter a military school, you will be an officer when you leave school. The so-called officers are cadres and management.
If an armed force department comes to your school to recruit non-commissioned officers directly, you will become a non-commissioned officer (graduated non-commissioned officer, non-graduated corporal) after joining the army. At present, the highest rank of non-commissioned officers in our army is grade seven. Corporal is 1 and sergeant is 2. The so-called non-commissioned officers are those who assist officers in management, and there are also non-commissioned officers of other professions. Petty officers are also called volunteers.
Those who enlist in the army through winter conscription are conscripts, that is, the group with the lowest status, the least allowance, the most jobs and the largest number in the army. At present, the service period of conscripts is only two years. During two years, you have the opportunity to enter the military school and become an officer when you come out. There are also opportunities to directly promote cadres (all cadres are promoted). Of course, this opportunity is very, very slim. You can also choose to be promoted to non-commissioned officer after the expiration of your service. At present, the conditions given by the army are that college students who are recognized by the state as secondary colleges or above can be directly promoted to non-commissioned officers.
I hope you are satisfied with my answer. Welcome questions.
