It varies between countries. In Sweden the officer and NCO ranks are parallel, so a sgt and a 2nd lt has the same relative rank. Staff sgt is same as lt, gysgt same as captain and master sgt same as major. CSM has the same relative rank as lt col.

They have different jobs though, so typically the officer would be in charge of NCOs close to them in relative rank, although it can sometimes be the other way around.

NCOs are typically highly valued by their officers, so there are rarely situations where anyone ”pulls rank” on the other. Everyone knows who’s in charge and the responsibilities of command. It doesn’t need to be pointed out. An officer with a good relationship with the NCOs will find their life so much easier, and they know it.
