The EOD—explosive ordnance disposal—community is tight-knit, and when one of their own is hurt, an alarm goes out. When Brian Castner, an Iraq War vet, learns that his friend and EOD brother Matt has been killed by an IED in Afghanistan, he goes to console Matt's widow, but he also begins a personal investigation. Is the bomb maker who killed Matt the same man American forces have been hunting since Iraq, known as the Engineer?
In this All the Ways We Kill and Die: An Elegy for a Fallen Comrade, and the Hunt for His Killer, Castner takes us inside the manhunt for this elusive figure, meeting maimed survivors, interviewing the forensics teams who gather post-blast evidence, the wonks who collect intelligence, the drone pilots and contractors tasked to kill. His investigation reveals how warfare has changed since Iraq, becoming individualized even as it has become hi-tech, with our drones, bomb disposal robots, and CSI-like techniques.
