Final answer:
Whether a manual 348 form must be maintained alongside a GCSS version depends on the military branch or unit's specific policies and SOPs, which can vary.
Step-by-step explanation:
The requirement to maintain a manual 348 form even if one exists in the Global Combat Support System (GCSS) can depend on the specific policies and procedures of the military branch or unit in question. The GCSS is designed to provide an automated way to track supply and logistics data, which may reduce or eliminate the need for manual records. However, there can be cases where redundancy is required for audit purposes or where digital systems are not fully trusted or operational. Therefore, it's essential to refer to the specific regulatory guidance or unit standard operating procedures (SOPs) regarding documentation requirements.
