This week, the “Breaking Doctrine” podcast team welcomed I Corps Commanding General LTG Matthew McFarlane and CSM Jonathan Reffeor for an in-depth discussion on translating FM 3-0 into action within the Indo-Pacific theater. Our hosts covered a number of topics including the I Corps’ strategic shift toward dynamic, land-based sea denial and “Archipelagic Defense”; the critical role of “Operation Pathways” in overcoming multinational friction and building unity of effort; the harsh realities of contested logistics; and leaders’ relentless focus on Soldier fundamentals while operating in a complex multidomain environment. Stay tuned, we expect this episode to post in early July!

ADN 1-26: Evolving the Command Post to Employ C2 Nodes
This video explores the critical evolution of Army command and control with the release of Army Doctrine Note (ADN) 1-26, "Employing Command and Control Nodes." On a modern battlefield defined by persistent surveillance and long range precision weapons, the traditional, large-scale command post has become a significant liability. ADN 1-26 provides a framework for transitioning from a single, static headquarters to a distributed network of smaller, more resilient C2 nodes. This shift focuses on two key areas: survivability and effectiveness. Learn about the eight interdependent factors leaders must manage including mobility, dispersion, and signature management, to protect the C2 system without sacrificing operational momentum. The video also details how commanders can tailor C2 nodes. Discover the next steps your unit can take to revise SOPs, build standardized equipment kits, and train for the future of warfare. To survive and win, the command post must evolve, and ADN 1-26 explains how.
