The Marine Corps has identified the young warrior lost at sea off California’s coast—a 21-year-old infantryman from Minnesota whose commitment and courage carried him across oceans in service to the nation.

Lance Cpl. Armando Ortiz Canseco vanished on June 25 while serving aboard the amphibious transport dock USS Anchorage.

He was in the midst of pre-deployment training exercises with the 13th Marine Expeditionary Unit and the Makin Island Amphibious Ready Group when he went missing.

Despite an immense effort spanning sea and air, Ortiz Canseco was declared dead two days later following a relentless 43-hour search.

The Marine Corps, Navy, Air Force, and Coast Guard combed roughly 2,400 square miles of ocean in the urgent effort to find him, employing multiple ships and aircraft in a race against time.

The operation ended only after it became clear that the odds of recovery had turned grim. The Navy shifted to recovery operations on June 26, and the young Marine was officially declared deceased on June 27.

As is standard in such cases, the Marine Corps has launched a full investigation into the circumstances surrounding his disappearance.

No details have yet been released about how or why the tragedy occurred, but service members and families across the branch are demanding answers, as they always do when one of their own is lost without explanation.

Colonel Richard Alvarez, commanding officer of the 13th Marine Expeditionary Unit, issued a heartfelt statement that cut straight to the spirit of the Corps.

“On behalf of the Marines and sailors of the 13th Marine Expeditionary Unit, I extend our deepest condolences to the family and loved ones of Lance Cpl. Ortiz Canseco,” Alvarez said.

“He earned the title of United States Marine and served his country with honor and commitment. We mourn alongside his family, and we remain committed to bringing him home.”

Ortiz Canseco’s journey through the Marine Corps was still in its early chapters.

Having enlisted just last year, on April 3, 2023, he went through the Corps’ rigorous West Coast boot camp at Marine Corps Recruit Depot San Diego. There, he proved himself worthy of the title every young recruit yearns to earn—Marine.

After graduating, he continued his training at the School of Infantry – West, where he specialized as a rifleman. He was assigned to 2nd Battalion, 1st Marine Regiment and later to 2nd Battalion, 4th Marine Regiment, both stationed at Camp Pendleton.

In that short but devoted window of service, Ortiz Canseco demonstrated the grit and dedication that define Marines everywhere—a commitment recognized through the Marine Corps Good Conduct Medal and the Sea Service Deployment Ribbon.

Tributes poured in from leaders across the Navy-Marine Corps team. Capt. Gary A. Harrington, commodore of Amphibious Squadron 7, emphasized the bond shared between the two branches.

“The amphibious Navy exists to fight alongside the Marine Corps, and a loss to the Marine Corps family is a loss to our own. We are a resilient force, and we continue to stand shoulder-to-shoulder in support of Lance Cpl. Ortiz Canseco’s loved ones and our ongoing recovery operations,” Harrington said.

For many across the nation, the story hits close to home. Ortiz Canseco wasn’t just a name on a roster—he was one of the next generation of American defenders willing to step forward when so many others stand back.

At only 21 years old, he represented what still makes the United States military the most capable fighting force in the world: young men and women ready to face danger, embrace sacrifice, and serve something larger than themselves.

Even in tragedy, the Corps rallies around its own. Marines know that the sea can be as unforgiving an enemy as any battlefield, but it also honors those who test its limits.

The 13th MEU’s continuing recovery efforts and commitment to bringing Ortiz Canseco home reflect the deep-seated Marine tradition of never leaving a brother behind.

This loss serves as a sobering reminder that service doesn’t just mean danger on foreign shores. Even in times of peace, the demands and risks endured during training or deployment preparation are immense.

These young men and women carry the weight of national defense in every moment, whether training off California’s coast or standing guard abroad.

While politics often swirl around military operations, the story of Lance Cpl. Ortiz Canseco cuts through all that noise.

It’s about service, sacrifice, and a family’s loss—and about a Marine who stepped up to serve a country he loved. The flag that drapes his casket represents not just one Marine’s life, but the unbroken line of American warriors before him.

The Marine Corps community, from Camp Pendleton to the far reaches of the Pacific, will remember Ortiz Canseco. As they say in the ranks, a Marine may fall, but the legacy of his courage stands eternal.

Lance Cpl. Armando Ortiz Canseco has joined the ranks of those who gave everything in service to this nation—and America will not forget him.
