I can't. The political commissar is mainly responsible for army building, but it is certainly not up to the political commissar to promote a company commander, because the army is going to fight and its military quality is also very important. The head of the regiment is responsible for military command, military operations, political work and daily ideological education. Of course, this is the matter of the political commissar, and the troops cannot have the final say, because the head of the regiment is also the political head of the regiment.
