In this episode of The Operational Arch, hosts Spencer Bates and DJ Taylor sit down with Lieutenant General Chun In-bum (Ret.), former commander of the Republic of Korea Special Warfare Forces and U.S. Army War College graduate, for a wide-ranging conversation on the enduring U.S.-ROK alliance. General Chun explores the deep historical, cultural, and security ties that bind the two nations — from Korea's democratic founding under American mentorship to the shared sacrifices of the Vietnam War. The discussion shifts to the operational challenges of the Korean Peninsula, including terrain, deterrence, the importance of adaptive planning, and the combined Second Infantry Division as a model for allied partnership. The episode closes with a sobering look at North Korea's battlefield performance in Ukraine, the growing Russia-DPRK relationship, and General Chun's call for greater focus on civil-military relations and cognitive warfare as the defining challenges of the modern era.

In this episode of The Operational Arch, hosts Spencer Bates and DJ Taylor sit down with Steven Box, founder and CEO of Vanguard Tactics and a top-ranked competitive Warhammer coach, alongside SAMS professor Matt Yandura. The conversation explores how Box's "IDEA" framework — developed over years of competitive tabletop wargaming and coaching — maps surprisingly well to military decision-making: gathering the right information under time pressure, making rapid decisions, executing with composure, and assessing outcomes to adapt. The episode also digs into why SAMS invited an outside expert from a non-traditional field and what operational planners can learn from embracing failure, coaching others, and considering future operating environments.

In this episode of The Operational Arch, host Major DJ Taylor hands the mic over to three key SAMS leaders: Mr. Kirk Dorr (Deputy Director of the School of Advanced Military Studies (SAMS)), Dr. Bruce Stanley (Director of the Advanced Military Studies Program (AMSP)), and Colonel Paul Godson (Deputy Director of AMSP). Together, they pull back the curtain on the Advanced Military Studies Program, covering what it is, what it produces, and exactly how officers can go from being curious about the program to becoming a competitive applicant. They dispel myths about AMSP as merely a "planners' school" and show how the program develops leaders to meet the Army's most demanding missions as experts in Army and joint doctrine, leading diverse operational planning teams, and enabling senior leaders. The ten-month program focuses on warfighting, operational art, and the critical and creative thinking required to anticipate and adapt to rapid change on the modern battlefield.
