The U.S. Army Reserve is currently evaluating whether it can deploy police forces, medical personnel, and other support units to the U.S. Southern Command within the next four months, according to an internal Army message reviewed by CBS News. U.S. officials, speaking on condition of anonymity, told CBS News that the request is part of ongoing military planning related to Cuba. However, the document does not indicate that any units have received formal deployment orders. This planning takes place amid the Trump administration's efforts to increase economic pressure on Cuba and push for political reforms on the island. The message reviewed by CBS News does not specify how many troops might be needed or where they might be deployed. The U.S. Southern Command’s area of responsibility includes Central and South America, as well as the Caribbean. The Army Reserve headquarters is seeking feedback from subordinate commands about the availability of six different types of military formations that could be used in the region. These include combat sustainment support battalions, which manage logistics like transportation and supplies, and engineer battalions. The message also calls for an expeditionary sustainment command to oversee logistics across a military operation, a medical brigade to coordinate medical units, and a forward resuscitative and surgical detachment to provide emergency care closer to U.S. forces. Additionally, the Army Reserve is looking for a military police brigade, which would handle security and law enforcement tasks. The U.S. Southern Command did not comment on the planning details, citing operational security concerns. Earlier this year, U.S. military personnel told CBS News that American forces had conducted reconnaissance operations in the waters surrounding Cuba, and that U.S. airpower components had been placed on high alert. However, those plans did not result in any deployments. Meanwhile, U.S. intelligence officials have been assessing how Cuba might respond to potential U.S. military actions, particularly as the Trump administration has accused Havana of strengthening ties with countries like Russia, China, and Iran. The Trump administration has been pursuing a more assertive foreign policy in the Western Hemisphere, often referred to as the "Donroe Doctrine," a modern version of the Monroe Doctrine aimed at curbing foreign influence in the region. This approach has led to increased military activity, including joint operations with countries like Ecuador to dismantle criminal networks. However, some legal experts have criticized recent U.S. military strikes in the Caribbean and Pacific, which have resulted in the deaths of over 230 people, as potentially illegal due to the risk of civilian casualties. Meanwhile, the Trump administration has imposed sanctions on Cuban entities and officials, including those involved in the country’s nickel industry, and has called for a "fundamental change" in Cuba’s government. Cuban officials have strongly opposed these actions, calling them "aggression" and "economic warfare."
