Press Release

SEVENTEEN TO A MAN BY DR. WILLIAM RANKIN BRINGS A POWERFUL LIFE STORY OF SURVIVAL, SERVICE, AND TRANSFORMATION

A Powerful Memoir of Courage, Survival, and the Price of Becoming a Man

In a memoir as raw as it is inspiring, Dr. William Rankin takes readers deep into the crucible of the Vietnam War and the American heartland that shaped him. Seventeen to a Man is not merely a war story; it is a profound testimony of transformation, tracing a boy’s journey from the dusty backroads of Texas to the deadly jungles of Southeast Asia, and finally to a life dedicated to teaching others how to defend themselves and find peace.

With unflinching honesty, Dr. Rankin recounts a childhood marked by poverty, an absent father, and a near-fatal three-story fall that left a permanent dent in his skull, an event he believes was a divine lesson. By the age of seventeen, seeking purpose and escape from the violent streets of New York City, he made a decision that would define the rest of his life: he enlisted in the United States Army.

Seventeen to a Man follows Dr. Rankin through basic training, where he earned sharpshooter honors, and into the specialized world of military communications. But his true education began when he arrived in Vietnam, barely three months past his eighteenth birthday. Assigned to the 1st Infantry Division and later to III Corps headquarters, he quickly discovered that the Army’s rulebook meant little in the face of guerrilla warfare. Unwilling to be a passive participant, he sought out Korean soldiers known for their hand-to-hand combat skills and trained with them unofficially, earning a reputation that would follow him through the war.

It was during this time that Vietnamese allies gave him the nickname Denki Dow, “Crazy.” For Dr. Rankin, it was a badge of honor, a recognition that he was willing to go where others hesitated. The memoir details harrowing patrols, the shock of the 1968 TET Offensive, and the unforgettable image of a twelve-year-old Viet Cong soldier emerging from the bush with a machine gun, a moment that still haunts him today.

Yet the book’s most gripping passages come from an experience Dr. Rankin kept silent for decades: a classified, undocumented mission ordered by his own command. Sent alone into a hostile hamlet to “relieve the mayor of his duties,” he carried no rifle, only a .45-caliber pistol, a compass, and a double-edged knife. The operation was, by official record, a mission that never happened, but for Dr. Rankin, it was a pivotal moment that tested his survival instincts, his morality, and his faith. He returned alive, but the psychological weight of that day would stay with him long after he left Vietnam.

“I came back to piss you off, you son-of-a-bitch,” Dr. Rankin recalls telling his commanding officer upon his return, a moment of defiance that perfectly captures the rebellious spirit that both protected him and complicated his military career.

Despite the trauma, or perhaps because of it, Dr. Rankin has spent the decades since his service transforming his experiences into a force for good. After leaving the Army, he went on to serve twenty years in the U.S. Air Force, all while building a distinguished career in the martial arts.

Today, he is a 10th-degree black belt and the founder of Uchuno Shorin-ryu Karate, a system that blends traditional Okinawan martial arts with techniques he learned in the jungles of Vietnam. His expertise has been sought by some of the nation’s most elite law enforcement and federal agencies, including the FBI, CIA, Secret Service, and numerous police departments across Texas and beyond.

“I don’t teach fossilized training programs,” Dr. Rankin says. “I teach what works. The skills that kept me alive in Vietnam are the same skills I share with officers, agents, and everyday citizens who want to protect themselves and their families.”

The book’s title, Seventeen to a Man, reflects the core of Dr. Rankin’s message: that maturity is not granted by age, but forged in adversity. His journey from a curious, klutzy kid in Sinton, Texas, where he rode the rails and staged backyard battles with plastic soldiers, to a warrior who survived some of the Vietnam War’s most intense moments is a testament to the resilience of the human spirit.

“I wrote this book for my family, for my brothers who served, and for anyone who has ever wondered what it really takes to become a man,” Dr. Rankin explains. “There were moments when I didn’t think I’d see my next birthday. But I learned that courage isn’t about not being afraid, it’s about doing what needs to be done even when you’re terrified.”

The memoir also pays tribute to the people who helped him along the way: his mother, who signed his enlistment papers despite her fears; his wives, Delia, Judy, and Nancy, who each bore the weight of his silent battles; and fellow veterans Joe Bannon and Rich Kluck, whom he credits with helping him navigate the invisible wounds of war. It is a book about war, but it is equally a book about love, loss, and the bonds that hold us together when everything else falls apart.

Now in his late seventies, Dr. Rankin continues to teach martial arts and share his story with audiences across the country. Seventeen to a Man is his first published memoir, a work he says was inspired by his current wife, Nancy, who urged him to put his experiences down on paper.

“For decades, I disappeared inside my own home, reliving things no one should have to see,” he admits. “Nancy planted the seed. She told me, ‘Write it down. Let people know what happened.’ This book is the result, and I owe her more than I can ever say.”

Seventeen to a Man is available now through major online retailers and select bookstores. With its gripping narrative, unvarnished honesty, and timeless lessons on courage and redemption, the book promises to resonate with veterans, history enthusiasts, and anyone seeking a true-life story of triumph over adversity.
