Which commands are Unified commands?

• A. Navy fleets
• B. Individual service commands
• C. Marine commands
• D. Joint forces command, transportation command, and strategic command

Answer: (D)

Unified commands are joint commands that bring together forces from two or more military departments to carry out broad, enduring missions that require cross‑service coordination. The trio of Joint Forces Command, Transportation Command, and Strategic Command fits this idea because each is designed to operate with elements from multiple services to accomplish wide-ranging tasks: joint doctrine and interoperability efforts, global mobility and logistics, and strategic deterrence and global operations, respectively. In contrast, Navy fleets stay within the Navy, individual service commands are limited to a single service, and Marine commands are specific to the Marine Corps, so they don’t combine multiple services under one command. This is why the listed trio is identified as Unified Commands.
