SAN JUAN, PUERTO RICO — After three decades of military service, Col. Charles L. Decker ended his final command with the U.S. Army on June 23, 2026, following a change of command ceremony at Castillo San Cristóbal that also marked the transition of the U.S. Army Corps of Engineers Caribbean District to its new name and expanded mission as the U.S. Army Corps of Engineers Latin America & Caribbean District.
The conclusion of Decker’s command reflects a distinguished career that spanned multiple continents, numerous command and staff assignments, and a pivotal role in shaping the Corps’ modern presence in the Caribbean. His leadership guided the transformation of Task Force Virgin Islands Puerto Rico (TF VIPR) into a fully established USACE district – an achievement that laid the foundation for the district’s enduring mission and its newly expanded responsibilities across Latin America.
A lifetime of service
Service runs deep in the Decker family. His grandfather served with the 82nd Airborne Division during the D‑Day invasion and later with the XVIII Airborne Corps as an engineer in the Corps Headquarters’ Topographical Engineering Company. His father served with the 7th Special Forces Group (Airborne) during the Vietnam era. Though his grandfather passed before he was born, Decker carries his name and the legacy of two generations of airborne Soldiers.
“Their example inspired me to follow in their footsteps,” he said. “I’m proud to be third‑generation airborne.”
Decker’s own military journey began in 1996, when he was direct commissioned as an ensign in the U.S. Naval Reserve Civil Engineer Corps. Over the next three decades, he served across the Navy and Army, on active duty, and in the National Guard and Reserve, gaining a uniquely broad perspective that shaped his leadership style.
His assignments included roles with Naval Mobile Construction Battalion 24; multiple Special Forces Operational Detachments with the 19th and 20th Special Forces Groups (Airborne); operations and leadership positions across engineer, training, and special operations units; and key staff roles supporting the U.S. Army Corps of Engineers Huntsville Engineering Support Center.
He later served as commander of the 841st Engineer Battalion in Miami, Florida, and as the Defense Support of Civil Authorities plans officer for the 1st Mission Support Command in Puerto Rico. He deployed in support of Operation Noble Eagle and Operation Enduring Freedom, further broadening his operational experience.
A licensed Professional Engineer and Project Management Professional, Decker brought both technical expertise and operational depth to every assignment. That combination of engineering acumen, joint service experience, and mission‑focused leadership ultimately led to his selection in 2023 as the commander of Task Force VIPR – the organization that would evolve into the Caribbean District.
Building the Caribbean District
Decker led Task Force VIPR (pronounced “viper”) through a period of rapid growth, major civil works accomplishments, and complex disaster recovery missions. Under his leadership, the task force evolved into the Caribbean District, which reached full operational capability in 2024 and became USACE’s 43rd district and the first permanent civil works–focused district in the Caribbean since 1950.
Standing up a district while simultaneously delivering a $10 billion project portfolio required building teams, programs, and mission-support functions from the ground up. Decker’s leadership ensured the district not only met that challenge but exceeded expectations, completing a multi‑year transformation that positioned the organization for long‑term success.
His tenure saw the district take on some of the most significant infrastructure efforts in Puerto Rico and the U.S. Virgin Islands. Under his command, the district awarded the largest civil works contract in Puerto Rico’s history, a $1.078 billion construction contract for the Río Puerto Nuevo Flood Risk Management Project. The district also completed the $56.7 million deepening and widening of San Juan Harbor using zero‑emissions dredging.
The district also awarded a $57.4 million construction contract for the Caño Martín Peña Ecosystem Restoration Project and advanced the $500 million Río de La Plata project to safeguard residents of the municipalities of Dorado and Toa Baja.
Across the U.S. Virgin Islands, the district advanced multiple high‑impact projects, including the $81.8 million Savan Gut Flood Risk Management Project and progressed design and construction for several military projects across St. Thomas and St. Croix.
Reflecting on the transformation from TF VIPR to the Caribbean District, Decker described the experience as both humbling and deeply meaningful.
“The growth from a task force to the Caribbean District and now the Latin America and Caribbean District is extremely gratifying,” he said. “Having the privilege to be part of such an amazing team and help shape this historic unit was the honor of a lifetime and the best possible final assignment I could have hoped for.”
Transforming regional infrastructure and strengthening strategic readiness
Beyond major civil works, Decker championed regional water security and interagency collaboration. He hosted the first‑ever Caribbean Water Resources Summit, uniting more than 130 experts from federal, commonwealth, academic, and nonprofit sectors to address shared challenges such as drought, aging infrastructure, watershed degradation, and flood risk.
Decker also oversaw major advancements in military construction and strategic readiness. Under his leadership, the district delivered numerous upgrades to Army training centers at Fort Buchanan and Camp Santiago. These investments enhanced joint training capabilities, improved emergency response infrastructure, and strengthened the region’s strategic posture in support of U.S. Southern Command.
Looking ahead
Decker will transition back to reserve status until his official retirement in November 2026. He and his wife Monica plan to remain in Puerto Rico, the place they have come to call home and where they have lived the longest since marrying in 2005. With 11 moves over the past 20 years, the family is ready for stability, community, and continued service in new ways, he said.
Decker said he and his spouse plan to travel, spend time with friends and family, and continue making meaningful contributions to the island they love.
Decker leaves behind a legacy of steady leadership, mission focus, and a district poised for its next chapter across the Western Hemisphere.
