Subject Matter Expert

Emergency physician Dr. Ashely Alker joins Subject Matter Expert to unpack her new book “99 Ways to Die”—a funny yet essential guide to the risks people actually face and how to avoid them. 

We cover everything from heart attacks and strokes to deadly infections and “butt stuff.” Dr. Alker offers practical advice, myth-busting first aid tips, and the early warning signs that should send you to the ER right now. We also talked about her time working in public health around the world, while Marty over-shared about all of his medical misadventures.

Dr. Alker is an emergency medicine physician, medical communicator, and public-health advocate known for translating complex science into clear, actionable advice. Trained in molecular biology, public health, and emergency medicine, she has advised TV and film productions and delivered talks on how we misunderstand dying—and how to make smarter choices long before an ambulance is involved. “99 Ways to Die” distills years of experience in the ER into a practical field manual for everyday life.

Laser Wars Jared Keller joins Subject Matter Expert to break down the world of military lasers—what works now, what’s still wishful thinking, and how these futuristic weapons fit into real counter-drone, ship defense, and air-to-air protection missions. 

We get practical on the financial ramifications of directed energy weapons, magazine depth against drone swarms, and the unsexy limits that matter (power, beam control, cooling, weather). We also hit current headlines, from shipboard lasers in contested waters to how realistic railguns are—and map out what to watch in outer space.

Jared Keller is the writer behind Laser Wars, an up-and-coming Substack focused on directed-energy weapons and futuristic defense tech. A longtime national-security reporter and former managing editor at Task & Purpose and Military.com, he translates defense-industry claims into plain English, pressure-testing vendor hype against physics, logistics, and real-world concepts of operation.

In this episode

• ​Lasers vs. drones: cost-per-shot and “infinite magazine” reality
• ​Where lasers actually slot in a layered air defense (EW + kinetic + DE)
• ​Ground, sea, and air use cases: what’s deployable vs. developmental
• ​Power & thermal management: the boring stuff that decides winners
• ​Law & escalation: dazzling optics, blinding bans, and gray-zone fights
• ​12-month forecast: what capability becomes routine—and what remains hype
• ​Will we ever have a Star Wars-esque lightsaber?!

Retired U.S. Army Lt. Col. Charles “Charlie” Faint joins Subject Matter Expert for a wide-ranging conversation about turning intelligence into action for special operations, building leaders who perform under pressure, and reading the world’s most volatile flashpoints. 

We unpack how SOF integrates intelligence, surveillance, and reconnaissance with decision-making at speed, what “good” leadership looks like when stakes are high, and how to read Indo-Pacific gray-zone clashes, Israel–Gaza dynamics, and Venezuela tensions without the hype.

Charlie is a former Infantry and Military Intelligence officer with 27+ years of service and seven combat tours in Iraq and Afghanistan. Charlie served with 5th Special Forces Group, the 160th Special Operations Aviation Regiment, and JSOC. He later taught at West Point (Modern War Institute), has advanced degrees, including an M.A. in International Relations, and leads veteran-focused projects such as The Havok Journal and the Second Mission Foundation. His work sits at the intersection of operations, strategy, and leader development.

• How SOF actually fuses intel with combat operations

• The targeting method that changed the War on Terror

• Trust, standards, and moral courage in the military

• Indo-Pacific alliances, gray-zone coercion, and deterrence signals

Author Geraint Jones joins Subject Matter Expert to take us inside the research behind his World War II nonfiction: ”Voices of Victory” and “The D-Day Tapes,” as well as his novels about Roman Legionnaires. 

We dig into how his work collected World War II oral histories, what veterans remembered from D-Day beyond the beaches, and the small details like terrain, logistics, and the damn mosquitoes that separate myth from reality. Then we jump centuries back: Roman tactics, the life of a legionnaire, and how archaeology, ancient literature, and his own experiences as a combat veteran shape the stories on his pages.

A British combat veteran turned New York Times bestselling author, Geraint Jones served as an infantryman and later worked as a security contractor before writing full-time. His books span WWII oral history, gritty Roman warfare, and contemporary soldier memoirs.
