The U.S. Army Reserve is reportedly assessing the readiness of certain military police, medical, and support units for a potential deployment as early as late December in connection with possible military operations involving Cuba. An internal Army message, reviewed by multiple news outlets, requested commanders to provide status updates on various units that might be required within a 90- to 120-day timeframe. While the message itself did not specify Cuba, anonymous U.S. officials indicated that the communist island is the focus of current military planning.

The units in question include a support battalion responsible for logistics such as transportation, maintenance, fuel, and supply coordination. Additional units under review reportedly include an engineer battalion and a medical brigade, which would encompass a forward surgical detachment capable of providing trauma care.

A spokesperson for U.S. Southern Command (SOUTHCOM), which oversees military operations throughout Central and South America and the Caribbean, declined to confirm details or comment on any operational movements or deployment timelines, citing operational security. The spokesperson noted that SOUTHCOM continually coordinates with the Joint Force to evaluate a wide range of potential requirements within its area of responsibility to support assigned missions.

These developments come amid stepped-up U.S. pressure on Cuba during the second term of President Donald Trump, under what officials have dubbed the “Donroe Doctrine,” emphasizing a more assertive stance in the Western Hemisphere. Prior to the recent United Nations General Assembly (UNGA) meeting, the Trump administration implemented stringent sanctions targeting Cuban entities and officials, including military research and development groups tied to the nation’s nickel mining industry.

At the UNGA on Tuesday, President Trump called for “fundamental change” in Cuba and predicted the fall of the current Cuban government, declaring that “freedom will be coming to Cuba.” His remarks prompted the Caribbean delegation to walk out in protest. In response, Cuban President Miguel Diaz-Canel condemned what he described as "aggression" and "economic warfare," accusing the United States of intentionally blocking oil imports.

Earlier this year, in March, Trump made a controversial statement declaring that he would have “the honor of taking Cuba,” indicating an openness to exerting control over the island, though specifics were not provided.

The situation underscores growing tensions between Washington and Havana, with the U.S. military appearing to prepare for a range of contingencies involving Cuba, though official sources remain tight-lipped about the precise scope and objectives of these plans.
