How to remove actors via trigger?

[Exfyre]

I either need to know how to remove actors via trigger, or how to give a unit a nonexistent actor that isn't a "sphere".

Thanks for the help

EDIT:
Maybe it would help with some context. Im trying to create an actor for a created unit that is exactly the same as a different unit.
I dont want to have to create a new, identical actor in the Data Editor for each unit. I want it to create the unit with no actor and add the actor from its pair via triggers.
