What are the two types of service requests in the requisition process?

The correct choice identifies the two main categories that encompass the types of service requests made during the requisition process in the context of the USMC supply chain. Maintenance refers to the actions needed to keep equipment in good working order, ensuring that operational readiness is maintained. Supply encompasses requests for materials and supplies necessary for operational tasks. Together, these categories represent the fundamental requirements for sustaining military operations.

Understanding that maintenance and supply are integral elements of the requisition process helps emphasize the importance of systematic management of resources, ensuring that units have both operational capability and necessary parts or materials for ongoing tasks. This categorization aids in prioritizing requests and managing resources effectively within the military logistics framework.
