Which item is loaded by the CMBRE in addition to mission planning?

• A. GPS crypto keys
• B. Test adapter unit
• C. Guidance data
• D. Digital map data

Answer: (B)

When preparing for a mission, you load items that enable hands-on testing and verification of the system, not just data. The test adapter unit fits this purpose because it provides the necessary physical and electrical interfaces to connect test equipment to the system under test, allowing functional checks, signal verification, and calibration during preflight and rehearsals. The other options—GPS crypto keys, digital map data, and guidance data—are data or security elements used for operation and navigation, but they don’t serve as the hardware interface needed for testing. So the item loaded by the CMBRE in addition to mission planning is the test adapter unit.
