Who is responsible for acquiring and maintaining the pallet couplers, plastic coverings, tiedown straps, and dunnage for deployment packages?

The deploying units are tasked with acquiring and maintaining the pallet couplers, plastic coverings, tiedown straps, and dunnage for deployment packages because their primary responsibility involves preparing and executing the logistical aspects of moving personnel and equipment to operational areas. This includes ensuring that all necessary components for securing and protecting the cargo are in place before deployment.

These units play a crucial role in the overall logistics chain, as they are directly engaged in the preparation of deployment packages, which require specific equipment for safe and efficient transport. Their focus is on operational readiness, making their responsibility for maintaining these items vital to successful deployment operations.

The other choices pertain to different aspects of the logistics process. Logistics units typically handle broader logistical planning and support; transport units focus on the actual movement of goods; storage units are responsible for warehousing and inventory management, rather than the preparation for deployment. Thus, it is the deploying units that are explicitly involved in the maintenance of the items mentioned in the question.
