The SCLSIS database is used to determine which of the following?

The SCLSIS (Supply Chain Logistics Support Information System) database plays a crucial role in managing logistics and supply chain information for various aspects of military or naval operations. It is designed to provide comprehensive support by identifying necessary resources and documentation needed for onboard systems.

This includes several key areas:

1. Technical Manuals: SCLSIS helps determine which technical manuals are necessary for equipment maintenance and operation while onboard, ensuring that personnel have the correct references to perform their duties effectively.

2. Test Equipment: The database also identifies what test equipment is needed, which is essential for the maintenance and operational readiness of onboard systems. Having the right test equipment ensures that any issues can be diagnosed and resolved promptly.

3. PMS Documents: Additionally, SCLSIS outlines which Planned Maintenance System (PMS) documents are required. PMS documents provide guidance on maintenance schedules and procedures, which are vital for ensuring that systems remain operational and adhere to safety and readiness standards.

The option that encompasses all these aspects reflects the comprehensive nature of the SCLSIS database in supporting logistics and operational readiness, making it the correct answer.
