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

The two main types of service requests in the requisition process are indeed Maintenance and Supply.

Maintenance requests pertain to the activities involved in keeping equipment and systems operational. This can include repairs, inspections, and any necessary updates to maintain functionality and readiness. On the other hand, Supply requests focus on acquiring the materials, parts, or equipment needed to fulfill the operational requirements of the Marines. This encompasses everything from ordering inventory to ensuring that essential items are delivered when and where they are needed.

Understanding the distinction between Maintenance and Supply is crucial, as they cater to different but complementary aspects of operational readiness. Maintenance ensures that all equipment is functional and ready for use, while Supply ensures that necessary parts and materials are available to support operational activities. This coordination between these two areas is vital for the seamless execution of military operations.
