This article by Brian Michelson via The Strategy Bridge discusses the idea that we are relatively accepting of warbots in roles such as reconnaissance, selective strike and logistics support, however there remains a level of discomfort with incorporating warbots into primary combat roles.

To stimulate discussion and debate, authors from the Defence Studies Department, Kings College London, have put together a series of articles. In the first article via Defence in Depth, Dr Stuart Griffin argues that both the operational art and the operational level of war are still relevant.

This document via the United States Air Force College provides a concise 1 1/2 page explanation of each of the levels and how they relate to one another.
