Outgoing Caribbean District Commander Col. Charles Decker, incoming Latin America & Caribbean District Commander Lt. Col. Nate Weander, and Jacqueline Keiser, deputy for Programs and Project Management for the Latin America & Caribbean District, listen to remarks during the June 23, 2026, change of command ceremony at Castillo San Cristóbal in San Juan, Puerto Rico. The event marked both the redesignation of the former Caribbean District as the Latin America & Caribbean District and Weander’s assumption of command, launching a new chapter for USACE’s regional mission spanning Puerto Rico, the U.S. Virgin Islands, and 33 partner nations across Latin America and the Caribbean.
