Exposing UObject derived class variables in Editor

I have a class called AmmoPouch, which is basically a collection of uint16s. I would like to expose these variables in the editor, but I cannot seem to find the correct UCLASS, or UPROPERTY specifier. Currently I can only see the class itself in the Editor, but I would like to see its variables as well. An example would be the USceneComponent class, which has a drop down that shows it’s variables.
