Professional Biography
Andrew “Andy” Anderson, M.D., is a professor of emergency medicine, practicing emergency physician, law-enforcement officer, tactical medical educator, and firearms instructor whose work connects clinical trauma medicine with defensive-firearms education.
Anderson began his medical career as a field EMT and paramedic before attending medical school. He subsequently spent more than two decades practicing emergency medicine at the University of Mississippi Medical Center, Mississippi’s Level I trauma center. His experience encompasses prehospital care, emergency medicine, trauma treatment, and the clinical realities of serious injury.
Law Enforcement and Tactical Medicine
Anderson’s tactical background complements his clinical practice. He has served as a deputy with the Lauderdale County Sheriff’s Department, previously worked as a special agent with the Mississippi Bureau of Narcotics, and served as a tactical physician for the AMR Tactical Response Team.
This combination gives him firsthand experience with both sides of the problem: the operational decisions surrounding armed encounters and the medical consequences that follow serious injury.
Tactical Anatomy
Within the firearms-training community, Anderson is particularly associated with Tactical Anatomy—the medically informed study of how three-dimensional human anatomy should affect defensive marksmanship, target interpretation, and expectations concerning physiological incapacitation.
His instruction builds on concepts developed by Dr. James S. Williams in Tactical Anatomy: Shooting With X-Ray Vision. Rather than treating the flat outline of a target as a complete representation of the human body, Tactical Anatomy asks students to understand the position, depth, angle, and protection of vital structures from different perspectives.
Primary & Secondary
Anderson joined P&S ModCast 464 — Tactical Anatomy Summit for a discussion connecting emergency medicine, three-dimensional anatomy, physiological incapacitation, and defensive-firearms training. His participation brings clinical and operational context to subjects that are often reduced to target diagrams or ammunition claims.
Professional Contribution
Anderson’s distinctive contribution is integrating decades of emergency-medicine experience with law-enforcement service and firearms instruction. He explains gunshot trauma and defensive targeting through anatomy and clinical reality rather than relying on two-dimensional target conventions, caliber mythology, or assumptions about immediate incapacitation.
