What military tactics are inherited from the cavalry?

I recently did a little research on one: deep operation. Previously, it was like this: the cavalry breaks the formation, wedges into the rear of the front and attacks the enemy's supply and infrastructure, thus paralyzing the entire front.
Currently, it is partially or completely replaced by tanks and motorized infantry.

What other tactics are inherited from the cavalry?

What does the cavalry have to do with it?
