Season 1 episode 10 of the Operational Arch is part two of our conversation with guest Dr. Jim Greer as he takes us on a deep dive into John Boyd and his Patterns of Conflict. We continue our conversation on how we should engage Boyd, and explores how John Warden's Five Rings theory collates with Boyd's theories. Boyd and Warden's theories remain complimentary in that they take a systems approach to understanding warfare, and may well be last pair of military theorists whose ideas substantively impacted how the U.S. Army conducts operations. Dr. Greer is currently a professor at the Advanced Military Studies Program. He served thirty years in the US Army, commanded at all levels from platoon through Brigade, is a prior director of SAMS, and is a veteran of six combat tours in Iraq, Afghanistan, Palestine and the Balkans. Dr. Greer retired as a COL and holds a Doctorate in Education from Walden University.
