How to create a prefab from multiple prefabs?

Question

Unity

There are several let's call them "sub-prefabs" of which a full-fledged prefab should consist.
Let me give you an example - there are prefabs of different running gears, there are different hulls, different guns. For example, tanks are obtained from them, that is, in order not to stamp all the variations, there are parts.
The question is how to implement it better - to initialize an object from several?
