Exposing the hidden failures of the military justice system through the eyes of a Marine who lived it, fought it, and challenged it. This is an insider’s account of how a system meant to uphold discipline too often betrays the very people who serve.
Battleground: Defending the Defenders is the definitive insider’s account of the systemic flaws within the military justice system. Written by retired Lieutenant Colonel Gary Barthel, a “Mustang Marine” who rose from the enlisted ranks to become a Judge Advocate, this narrative offers a rare dual perspective from both the battlefield and the courtroom.
The book uncovers the hidden battles of servicemembers caught in a system that often prioritizes bureaucracy and discipline over humanity and healing. Through a blend of raw personal stories and legal analysis, Gary exposes how political agendas and leadership failures can lead to the neglect of those who have sacrificed the most.
Battleground is organized into three powerful sections that provide both a critique of the current state of military law and a roadmap for its future:
Unlike academic texts or general military memoirs, Defending the Defenders pairs the grit of a Marine with the precision of a seasoned legal advocate. It does not just highlight problems; it honors the quiet heroes — Marines, leaders, and advocates — who continue to fight for fairness within an imperfect structure.
Growing up with a father who served in the Marine Corps was like living with a drill instructor. He instilled in each of us a clear belief: if you wanted something, you had to work hard and take good care of it. That hard work required discipline, teamwork, and a commitment to something greater than us.
Our team was our family. Our parents gave us love and happy memories, even though we didn’t have much money. We were expected to do our part at home and contribute to the family. My father required my brother and me to give him a small percentage of what we earned from our paper route to go toward family expenses. The rest we were expected to save, not spend on unnecessary things. Rain or snow, we were up at 5:30 a.m. delivering newspapers on our bikes.
His compassion came through on frigid mornings. When it was below zero, he would drive us in his car to keep us warm. But his drill instructor side emerged when it came to chores. He insisted everything be done with precision. If it wasn’t done right, we had to do it again.
For example, after we cleaned our bedrooms, he would inspect them. He’d run a finger along the top of the windowsill, and if there was dust, we’d be sent back to fix it. Once it passed inspection, we had to report back and let him know it was ready for a final review.
At the time, my four siblings and I thought he was being unreasonable and just harassing us. But as we got older, we realized he was teaching us discipline. He was preparing us to become responsible adults, ready to face the world. He taught us to work hard, to save what we earned, to meet financial obligations like rent and car payments, and to take care of the things we worked for. Most importantly, he taught us about teamwork. Each family member was part of the unit, expected to contribute and to share in the rewards.
