Overview
- On Friday, September 25, an internal Army Reserve message asked subordinate commands whether six types of support formations could be available on a 90–120 day timeline.
- The document does not mention Cuba or order deployments, but multiple U.S. officials told CBS News the query is part of ongoing planning focused on the island and Southern Command declined to discuss details for operational security.
- The six unit types named include a combat sustainment support battalion for logistics, an engineer battalion for construction and repairs, an expeditionary sustainment command to run theater logistics, a medical brigade and a forward resuscitative and surgical detachment for trauma care, and a military police brigade for security and detention tasks.
- The check follows earlier U.S. activity this year such as seafloor and maritime reconnaissance and heightened air readiness, and it comes as the administration has tightened sanctions and President Trump pressed for political change in Havana at the U.N.
- If forces were accelerated on a 90‑day clock, planners would face strain on reserve mobilization processes, potential need for congressional authorization, and humanitarian and regional risks that could affect Cubans and neighboring countries.
