Anyone familiar with tactical medicine knows the name Dr. Frank Butler—Navy SEAL, captain, ophthalmologist, former director of the SEAL biomedical research program, and one of the founders of tactical combat casualty care (TCCC).

Butler’s new book Tell Them Yourself: It's Not Your Day to Die is the extraordinary account of how a small group of world-class trauma experts joined forces with America's best combat medics to rewrite the rule book in battlefield medicine—and then to sell these revolutionary new concepts to a disbelieving medical world.

Mike McCabe gets some time with one of the most distinguished, decorated and influential medical minds in TCCC to discuss challenges and innovations in battlefield medicine and what those lessons can bring to civilian EMS.
