In this episode of Combat Story, AJ Pasciuti sits down with Matt Cavanaugh, retired U.S. Army Lieutenant Colonel, combat veteran, strategist, endurance athlete, and living kidney donor, for a conversation about what service really looks like when nobody's watching. Matt is the author of Best Scar Wins: How You Can Be More Than You Were Before, and his story goes far beyond combat. We start with his experiences in Iraq and the weight of leadership under pressure, then move into the harder-to-talk-about parts of life after war: grief, identity, responsibility, and the quiet choices that shape who we become. Matt shares why he decided to become a non-directed living kidney donor, donating to a stranger and helping spark a chain that saved eight lives, including a fellow service member. Not long after surgery, he took on an endurance challenge called 1K4D (One Kidney, Four Deserts) — nearly 1,000 kilometers of self-supported racing across Namibia, Georgia, Chile, and Antarctica, including moments where the heat hit 131°F and the margin for error disappeared. This episode isn't about highlight reels. It's about follow-through. It's about choosing discomfort for the sake of others, and what it takes to keep going when the "why" has to be bigger than you. If you're interested in combat leadership, post-traumatic growth, endurance mindset, or service beyond the battlefield, this conversation will stick with you. 🎙️ Guest Information — Matt Cavanaugh | Best Scar Wins Matt Cavanaugh, PhD, is a West Point graduate and retired U.S. Army Lieutenant Colonel/Strategist who deployed to Iraq with the 3rd Armored Cavalry Regiment, earning two Bronze Stars and the Combat Action Badge.
