SAN JUAN, PUERTO RICO — In a ceremony held June 23, 2026, at the historic Castillo San Cristóbal, the U.S. Army Corps of Engineers Caribbean District was officially redesignated as the U.S. Army Corps of Engineers Latin America & Caribbean District, marking the beginning of a new era for the organization and its expanding regional mission. Immediately following the redesignation and the unfurling of the new district colors, Lt. Col. Nathaniel Weander assumed command, becoming the first commander to lead the district under its new name and expanded area of responsibility. The ceremony also marked the departure of Col. Charles L. Decker, whose leadership guided the transformation of Task Force Virgin Islands Puerto Rico into the Caribbean District and ultimately positioned the organization for its redesignation as the Latin America & Caribbean District.
