COMMENTARY: Investing in Our Warfighters: The Imperative of Multi-Domain Readiness (UPDATED)
5/9/2025
By Sean S. Buck
June 3rd marks one year since I assumed the role of president of the National Training and Simulation Association. After more than four decades in uniform, I thought I had a solid grasp of the training and simulation enterprise — its breadth, its impact and its people. I quickly came to realize there’s always more to learn.
Over the past year, I’ve been privileged to witness firsthand the extraordinary innovation and collaboration taking place across our community. From TSIS in Orlando to I/ITSEC — the world’s premier modeling and simulation event — and across the Atlantic to IT2EC in Norway, I’ve had the honor of engaging with the thought leaders, engineers, warfighters and policymakers who are shaping the future of readiness.
What I’ve seen has reinforced a simple truth: we are standing at a pivotal moment. Technology is here. The demand for change is here. And our warfighters are ready. The question is — are we?
As we look ahead to an increasingly contested and complex security environment, one thing is clear: the nature of warfare has fundamentally changed. And with it, the way we prepare our force must change too. Multi-domain operations are no longer an abstract concept. They are the operational reality — where land, sea, air, space and cyberspace are engaged simultaneously and interdependently.
