In the sweltering rice paddies of the Mekong Delta on January 25, 1969, 90 American infantrymen lay trapped in the open, pinned down by a North Vietnamese machine gun bunker that had already killed their commander and four others—until a helicopter pilot in a cavalry hat decided to land on the problem.
First Lieutenant Allan “Ace” Cozzalio, flying a tiny O-6 Loach scout helicopter, dropped to just 10 feet above the enemy bunker as machine gun fire tore through his plexiglass cockpit. His rotor wash kicked dust from the sandbags. He did not retreat.
He landed on top of the bunker. His crew chief jumped out, dropped a fragmentation grenade through the firing port, and scrambled back aboard. Cozzalio pulled pitch and climbed as the bunker exploded beneath him.
The 90 men lived.
That moment, now 56 years ago, is at the heart of a renewed push to upgrade Cozzalio’s Distinguished Service Cross to the Medal of Honor. Surviving members of Charlie Company, 5th Battalion, 60th Infantry, wrote to the U. S.
Senate in 2024, saying they owe their lives to him.
Cozzalio was not a typical pilot. Born in 1946 on a cattle ranch along the California-Oregon border, he was drafted in 1966, volunteered for helicopter flight school, and arrived in Vietnam in December 1967. He flew the Hughes OH-6 Cayuse, nicknamed the Loach.
He wore a full 1860s cavalry uniform—blue coat, brass buttons, yellow silk scarf, white Stetson hat—and carried a genuine Civil War cavalry saber strapped to his belt. He used it to capture enemy soldiers wading in canals, probing the mud with the blade.
His call sign was Waragon 10. He treated his helicopter like a faster horse. He flew at treetop level, sometimes lower, skimming rice paddies so low the rotor wash revealed hidden bunkers and tunnel openings.
He made the enemy panic and shoot poorly.
In his first 18 hours of combat flying, he was shot down. He suffered a broken jaw and was evacuated to Japan for surgery. With his jaw still wired shut, he walked out of the hospital, found a C-130 heading back to Vietnam, and climbed aboard—AWOL.
His commanders did not court-martial him. They put him back in the cockpit. Over the next 18 months, Cozzalio was shot down five more times, surviving every crash.
He received every valor award except the Medal of Honor: the Distinguished Service Cross, Silver Star, four Distinguished Flying Crosses, Soldier’s Medal, two Purple Hearts, 48 Air Medals, and two Bronze Stars.
The peak came on January 25, 1969, near Fui Village. Charlie Company had been pinned for two hours. Cobra gunships tried to destroy the bunker but could not get the angle without hitting the Americans hugging the dirt 50 meters away.
Artillery could not reach it.
Cozzalio, circling overhead in his Cobra, assessed the geometry. The bunker’s machine gun was designed to fire horizontally, not vertically. He landed his Cobra, switched to a Loach, and descended directly onto the bunker.
Machine gun fire ripped through the canopy.
His crew chief kicked open the door, dropped the grenade, and dove back in. The helicopter lifted off just as the bunker exploded. A general officer who watched from a command-and-control helicopter landed immediately and promoted Cozzalio to captain on the spot, awarding him the Silver Star.
The Distinguished Service Cross followed on May 7, 1969. The citation called it extraordinary heroism. Cozzalio served two tours, logging more than 2,100 combat flight hours, most at altitudes where mechanical failure meant instant death.
He was denied a third tour because he repeatedly crossed the DMZ into Cambodia and Laos, pursuing enemy forces into unauthorized areas. The Army decided he was too valuable—and too reckless—to send back.
He remained in service, rising to lieutenant colonel, commanding the 4th Aviation Training Battalion at Fort Rucker, Alabama. The scout tactics he pioneered—low-level, aggressive, using the helicopter as bait—became standard U. S.
Army doctrine.
Even stateside, he stayed in character. At the Command and General Staff College, while other officers carried briefcases, Cozzalio carried saddlebags. At civic functions, he wore his 1860s cavalry uniform.
But the war took a hidden toll. In 1986, he contracted a rare virus that led to cardiomyopathy, a weakening of the heart muscle. The Army medically retired him after 20 years of service.
He returned to California, competed in team roping, and taught at a local college.
By 1993, his heart was failing. He moved to Portland, Oregon, to await a transplant. On April 27, he received a new heart.
The surgery went well. The next day, April 30, his new heart failed. He died at age 46.
April 30—the same day Saigon fell in 1975, the same day the Vietnam War officially ended. Cozzalio had escaped death six times in combat but could not survive peace.
In 2020, the Army Aviation Association of America inducted him into the Army Aviation Hall of Fame. The citation highlighted his role in developing scout tactics and embodying the spirit of army aviation.
The Pentagon is still reviewing whether to upgrade his Distinguished Service Cross to the Medal of Honor. Senators from multiple states have endorsed the effort. Dozens of surviving soldiers from Charlie Company support it.
General officers who flew in Vietnam back the upgrade. Lieutenant Colonel Hugh L. Mills Jr.
, a fellow scout pilot who was shot down 16 times, said of Cozzalio: “Ace was the eternal cavalry man. He lived and breathed cavalry. Some thought he was eccentric.
I thought he was the real deal.”
The O-6 Loach is still in service today as the MH-6 Littlebird, flown by special operations pilots using the same low-level tactics Cozzalio pioneered in 1968. They do not wear Stetsons or carry sabers, but they fly the way he taught—fast, low, and aggressive.
Cozzalio’s heart gave out at 46. But the spirit he brought to the battlefield—the refusal to accept that some things cannot be done, the willingness to land on the problem when everyone else flies away—never dies.
It just finds a new helicopter and a new pilot willing to take it lower than anyone else dares.
The men of Charlie Company remember. They wrote in their letter to the Senate: “We were running out of ammunition and time. Without him, none of us would have made it home.”
Eighteen signatures. Eighteen men alive today because a cattle-ranch kid from Oregon who wore a cavalry hat and carried a saber decided the book on how to fight wars was wrong. Sometimes, you just land on the problem.
