Which equipment item is not required in the CDF?

The correct answer is that infrared scanners are not required in the Contingency Deployment Facility (CDF). The CDF is primarily focused on the efficient management and processing of logistics resources during deployments, which typically includes equipment that directly assists in the handling and transportation of supplies and equipment.

Fixed or portable scales, shoring material, and portable lighting all serve crucial functions within the CDF's operations. Scales are essential for measuring the weight of cargo, which is critical for safe transport and compliance with weight limits. Shoring material is used to secure and support loads, preventing shifting or damage during transport. Portable lighting ensures that work can proceed efficiently in various conditions, especially in low-light environments during deployments.

In contrast, while infrared scanners can be beneficial for specific logistics operations, such as scanning barcodes or for safety inspections, they are not a fundamental requirement for the core logistical functions carried out in the CDF. Therefore, their absence does not impede the essential operations of the CDF.
