From which supply unit should paper be requested?

The correct choice is based on the specific function and inventory capability of the impact card supply unit. An impact card typically deals with items that are more specialized or part of a specific category of consumables, often related to operational needs. Paper, as a consumable resource, falls into this category.

The general store primarily focuses on a broader range of supply items and may not specifically manage paper products. The tool crib is dedicated to tools and maintenance equipment rather than office supplies. The demand processing unit plays a role in inventory management and order fulfillment rather than directly providing supplies to personnel. Therefore, the impact card provides a targeted approach for requesting paper, ensuring that the needs for office supplies are met effectively. This specialization makes it the most appropriate option for requesting paper among the listed units.
