Modern war is the conquest not only of an adversary’s territory but also of that adversary’s ability to observe his own situation, orient himself relative to the scene, decide on a response, and finally to act on that decision. Combined, these four processes form the OODA loop, a term coined by Air Force Col. John Boyd in a landmark 1987 briefing. Increasingly, the human OODA loop on the battlefield is giving way to a mechanical one. That emerging reality will present new opportunities and challenges for a military tasked with maintaining command and control against a wide variety of adversaries, across the globe. This eBook provides a snapshot of what those efforts look like, today and in the near future.
