subobjects & components - what's the difference


I’m seeing a lot of documentation that refers to subobjects & components. I understand that components are a type of subobject but I can find other type of subobject.

My goal is to set a manager of my pawn attributes and I thought about putting it as a subobject.
I think I can set it as a component, but I want to be sure that’s the right things to do.

My manager need replication so for the moment it’s an actor based class.
