If you are an on-the-job cadre, and then you get a doctorate, there is no distribution problem. You can go back to your old unit. Generally, those who can go to military schools to study for on-the-job doctors are business backbones with high education. Of course, after you graduate, you will continue to return to your original unit, and there is no distribution problem.
The last one is that doctoral students who have finished their undergraduate, master's and doctoral degrees in military schools belong to the military. Of course, when they graduate, they have to follow the national arrangements. Those who graduate to participate in the unified distribution of the whole army and obtain doctoral degrees shall be given appropriate posts and awarded the rank of major. Now, of course, it's not as rigid as it used to be. I assign you a position directly, but it's a bit like a two-way choice. For example, students fill in their volunteers first, and then the troops are allocated as a whole. Of course, before the allocation, there will be several units for you to choose from, and of course the units are also choosing you. Different from ordinary colleges and universities, these units are all military units. Including grass-roots units, organs, bases and military research institutes.
