Episode notes
Three Commands, One Complex Role
- Brunson wears three hats: UN Command to preserve the armistice, Combined Forces Command for bilateral crisis response, and USFK for forward-stationed U.S. forces.
- These roles overlap and can pull in different directions during resource or tasking disputes.
DMZ Risk Is Miscalculation, Not Solely Force
- The DMZ's danger is mainly miscalculation from unclear lines, moving markers, and new technologies like drones.
- Brunson emphasizes maintaining accurate shared data and regular mil‑to‑mil engagement to prevent inadvertent violations.
Combat Deployments Accelerate DPRK Learning
- Brunson sees North Korean deployment to Ukraine as a learning opportunity that accelerates DPRK tactics and tech adoption.
- He warns those combat lessons, especially on drones and small‑unit tactics, will be reimported into North Korean forces.
