Title: Create/Modify/Delete Units individually through API

Responses served to the client needs to be at the granularity that they mean something. Modifying & deleting units as big chunks without a more complex error response was not granular enough. This approach makes it obvious what has happened in response to a request and gives the client the ability to control the behavior on failure quite easily.

This is leaving the door wide open for batch requests in the future.
