The Army Reserve has asked commanders whether specific military police, medical and logistics units could be made available to U.S. Southern Command within 120 days as part of contingency planning reportedly tied to Cuba. The internal message requested six unit types but did not name Cuba as a destination, order deployments, or specify troop numbers. The inquiry follows earlier Pentagon reviews — including options involving the 101st Airborne — and comes amid U.S. concerns about Havana's ties with Russia, China and Iran.
Army Reserve Surveys Unit Availability in Contingency Planning Tied to Cuba

The Army Reserve has asked commanders to report whether certain military police, medical and logistics formations could be made available to U.S. Southern Command within 120 days, according to an internal message reviewed by CBS News. The notice did not name Cuba as a destination and did not order any troop deployments.
What the Request Asked
The internal inquiry asked commands to confirm availability of six types of units by Thursday: a combat sustainment support battalion, an engineer battalion, an expeditionary sustainment command, a medical brigade, a forward resuscitative and surgical detachment, and a military police brigade. Together, those formations could provide transportation and supplies, engineering support, medical care and security for a range of missions.
Context and Limitations
U.S. officials told CBS the outreach is part of contingency planning related to the island. The document did not specify how many personnel might be required or what precise mission those forces would carry out — it was an availability check, not an order to deploy. The inquiry does not indicate that the president or the Pentagon has approved any operation.
U.S. Southern Command, which oversees military activities across Central and South America and the Caribbean, declined to discuss possible troop movements or timelines with CBS, citing operational security. The command said it routinely assesses requirements with other military services. The Army Reserve did not respond to CBS before publication.
Related Planning and Regional Tensions
The request follows earlier Pentagon reviews focused on Cuba. In July, CBS reported officials examined options that included an Army-led air assault involving thousands of soldiers from the 101st Airborne Division; officials emphasized then that evaluating options does not mean a decision to execute them. In May, U.S. intelligence agencies were reported to be assessing how Cuba might respond to potential American military action.
Those planning efforts come amid heightened U.S. concerns about Havana's ties with Russia, China and Iran and measures by the administration aimed at restricting the island's access to fuel. At the U.N. General Assembly, President Trump said Cuba's communist government "will fall" and declared, "Communism will never be coming to America, but freedom will be coming to Cuba." He also said Marco Rubio was "deep into negotiations" with Havana and warned against foreign adversaries gaining a foothold near the United States.
Cuban Foreign Minister Bruno Rodríguez told The Associated Press that no meetings with U.S. officials were scheduled, while saying Havana remained open to contacts. He accused Washington of imposing an oil blockade and tightening economic restrictions that have worsened conditions for Cubans. Separately, the State Department is reportedly considering restrictions on travel by Cuban officials to the U.N.; those proposed measures have not been approved.
Bottom Line
This Army Reserve request is an availability check used in routine contingency planning. It identifies formations that could support logistics, engineering, medical and security tasks if needed, but it does not commit forces, specify troop counts, or announce any operational plan.
