Where in the GCU-30 is the TMU-72 placed to be refilled?

The TMU-72 is refilled at the Fill Station of the GCU-30. This specific location is designed to facilitate the refilling process of the TMU-72, which is essential for its operational readiness. The Fill Station is equipped with the appropriate connections and mechanisms to ensure that the refilling is done safely and efficiently, allowing for quick turnaround times and readiness for future deployments.

In contrast, other areas like the Refill Chamber, Charge Bay, or Storage Pod serve different functions. The Refill Chamber is typically used for holding or processing fluids rather than active refilling. The Charge Bay is focused on the charging of equipment, which is separate from the refilling process. The Storage Pod is meant for storing the TMU-72 when it is not in use, rather than engaging in active refilling. Therefore, the Fill Station is the designated and most appropriate area for the refilling of the TMU-72 within the GCU-30 framework.
