Which officers and men should be the supervisors of grassroots ethos?

Excellent officers and men. The selection and service of grass-roots supervisors at the grass-roots level is a window and mirror to observe the construction of the army's atmosphere, and it is also a solid guarantee for officers and men to have a sense of gain and happiness. Grass-roots supervisors should not only play a role in their work, but also play a role anytime and anywhere to drive comrades around them.
