What types of transactions can be processed directly through GCSS-A?

The correct answer focuses on the primary functions of the Global Combat Support System-Army (GCSS-A), which is designed to facilitate the management of supply chain operations within the Army. Supply requisition and property transfers are core activities of GCSS-A, allowing units to request necessary supplies and manage their property inventory effectively.

By processing these types of transactions directly, the system streamlines logistics and ensures that units can maintain operational readiness by having access to essential materials. This functionality is crucial for efficient supply chain management, as it reduces delays and enhances accountability regarding the distribution and use of Army property.

The other options pertain to activities that, while relevant to Army operations, do not fall under the direct transactional capabilities of GCSS-A. These might include more administrative, compliance, or external financial activities rather than the immediate logistical functions that GCSS-A supports.
