The US Army Reserve sends an internal message asking commands whether they can transfer six types of units to the US Southern Command, according to a report that cites a leaked Pentagon-related memo. The message reportedly goes out last week as part of planning that the outlets describe as preparation for possible operations connected to Cuba.

The reporting frames the request as indicating a broader military readiness effort, including mentions of specialized support such as battlefield surgeons and a timeline described as running toward Christmas. However, available details in the cited coverage do not specify the exact mission, location, or whether any transfers ultimately occur.

Other elements of the story—such as the purpose of the planning, the scope of the units involved, and the legal or operational triggers—are not fully substantiated in the provided excerpt and may differ depending on how outlets interpret the leaked information. Overall, the common thread across the reporting is the internal inquiry about unit handover capacity to Southern Command.
