In this episode of the Teamcast, Dr. Preston Cline and Dr. Art Finch discuss MCTI's most recent paper, “The Fourth Generation of Military Special Operations Selection and Assessment". Thanks to our collaborative inquiry community, we've received feedback and observations from special operations team members across the Five Eyes. Preston and Art reflect on that feedback and contrast the historical “psychological model” with rites-of-passage approaches. They cover the effort to sustain force numbers while still selecting the cognitively diverse candidates teams need. They discuss the balance between tacit knowledge and psychological science, and the need to avoid pendulum swings where either side dominates. You'll also hear what causes programs to erode unless leaders manage change intentionally.

Why This Episode Matters Now:

In 2022, the war in Ukraine revealed something our partners had been experiencing but we hadn't fully articulated: the traditional model of intact, homogeneous teams wasn't sufficient for the emerging operational environment. Individuals with diverse expertise, geography, language, and allegiances needed to rapidly converge into what we call Tactical Swarms—heterogeneous cross-functional units that form, solve emergent problems, and disperse.

Our recent white paper, The Fourth Generation of Military Special Operations Selection & Assessment, explores this evolution in depth. But six years ago, Preston laid the foundational concepts in this conversation with Coleman.

What the Research Shows:

Many operators who excelled at teamwork—performing with known, homogeneous teams—struggled with teaming: the ability to rapidly build cohesion within heterogeneous groups. This episode examines why routine versus critical communication and field observations across special operations, emergency medicine, and other high-stakes environments. In this episode, Preston and Coleman describe how tactical swarms and X teams differ from traditional team structures, and they distinguish between routine and critical communication and when teams must shift between them.

When a patient's heart or lungs fail, ECMO (Extracorporeal Membrane Oxygenation) technology can keep them alive—but only if the team operating it works flawlessly under pressure. In this episode, Thomas Preston draws on over 30 years of experience in cardiopulmonary care to reveal what it takes to manage these life-sustaining systems.

This Teamcast episode covers the specialized roles within ECMO teams, the critical relationship between perfusionists and other medical staff, and strategies for navigating crisis moments when seconds matter. Thomas discusses how trust, constant vigilance, and ongoing training form the foundation of successful outcomes in some of medicine's most intense situations.
