Army Reserve Canvasses Units for Possible Caribbean Mission as Cuba Planning Continues
An internal Army message seeks military police, a medical brigade, engineers and logistics commands that could be 'needed in 90-120 days' under Southern Command, U.S. officials told CBS News.
WASHINGTON — The U.S. Army Reserve is checking whether it can supply U.S. Southern Command with military police, medical teams, engineers and logistics units within the next four months, according to an internal Army message reviewed by CBS News, part of continuing military planning that multiple U.S. officials said is aimed at Cuba.
The message does not mention Cuba by name, and there is no indication that any unit has received deployment orders. But officials who spoke on condition of anonymity said the request is tied to planning for possible action around the island as the Trump administration ratchets up economic pressure on Havana and demands political reforms.
The document, generated last week, asks Army Reserve commands whether six types of formations would be available, saying they would "possibly [be] needed in 90-120 days." Commands were told to respond by Sept. 25. The list includes a combat sustainment support battalion that runs transportation, maintenance, fuel and supply; an engineer battalion; and an expeditionary sustainment command that oversees logistics across an entire theater. It also asks for a medical brigade, a forward resuscitative and surgical detachment that performs emergency trauma surgery close to front-line troops, and a military police brigade, the kind of unit that handles security, detention and law enforcement.
Southern Command, which covers Central and South America and the Caribbean, declined to discuss specifics. "Due to operational security concerns, we do not disclose details or comment on U.S. operational movements or potential deployment timelines," a spokesperson said, adding that the command "continuously coordinates with the Joint Force to assess a range of potential requirements." The Army Reserve did not respond before publication.
The request builds on months of preparation. Earlier this year, U.S. forces carried out reconnaissance of the seafloor and maritime approaches around Cuba, and U.S. air units were put on heightened readiness and told to pre-stage personnel, plans that did not go forward. In May, U.S. intelligence officials were assessing how Cuba might respond to American military action, and in July, planners examined options that included an Army-led air assault by thousands of soldiers from the 101st Airborne Division. Officials stressed at the time that the briefings did not mean the president had decided to act.
The administration has accused Havana of deepening ties with Russia, China and Iran, although the intelligence community's 2026 threat assessment describes Cuba mainly as an enabling environment for larger rivals rather than a threat in its own right. President Trump has pushed what officials call the "Donroe Doctrine," a more aggressive U.S. posture in the Western Hemisphere. On Thursday, U.S. troops and DEA agents helped Ecuador arrest more than 30 members of Mexico's Jalisco New Generation Cartel, and since last September the military has killed more than 230 people in some 70 strikes on alleged drug boats in the Caribbean and eastern Pacific, operations some legal experts call extrajudicial killings.
