Stuart Elden has a short article on Chamayou's Manhunts. It is both interesting in terms the explicating Chamayou's work (where Elden quickly ties together Manhunts, with the later work on drones), but also connecting Chamayou's work to Elden's work on territory. Which is a good time to tell you all to read Elden's The Birth of Territory, if you haven't already.
I earlier reviewed Chamayou's Manhunts, and discussed it's relationship to critical animal studies, here.
