Description:

The USMC requires an enterprise-wide capability to automate the collection, entry, and reporting of PEI maintenance and operational data through an Electronic Weapon Record Book (EWRB). The absence of this capability will result in a critical data gap adversely impacting the Ordnance community’s ability to track and analyze key metrics such as round counts, effective full charge, pullover gauge measurements, maintenance costs, availability, and readiness for weapon systems. This data is essential to inform decision-making across strategic, operational, and tactical levels of command and to support life cycle management and resource allocation decisions. Additionally, the capability must extend beyond the Howitzer community to accommodate broader USMC ground equipment and weapons platforms, while incorporating role-based access control to safeguard data integrity. Without this integrated and customizable EWRB capability in ELMS, the Marine Corps risks losing visibility into critical performance metrics, reducing the effectiveness of sustainment planning and readiness reporting. The absence of this capability in ELMS represents a Significant Deficiency, as it limits USMC's ability to track and report maintenance and operational data for serialized ordnance assets. This impairs readiness reporting, life cycle decision-making, and auditability across weapon systems.

Recommended:

REQ-001 - Electronic Weapon Record Book Capability. ELMS shall provide an Electronic Weapon Record Book (EWRB) capability to collect, store, and report serialized ordnance data, including component configuration, inspection results, and firing data. Supports data-driven decision-making for life cycle management and readiness reporting of Marine Corps weapon systems. Users can enter, update, and report weapon-specific data (e.g., round count, component swaps, EFC) for serialized equipment.

REQ-002 - Parent-Child Quality Record Structure. ELMS shall implement a parent-child data structure for weapon records, allowing summary data roll-up from child entries (e.g., Gun Book Part I and II) to the parent weapon header. Enables accurate aggregation of inspection and firing metrics for each weapon system. Child entries (e.g., Pullover Gage, EFC) are reflected in summary fields on the parent record automatically upon save.

REQ-003 - Weapon Component Tracking and Swap Logging. ELMS shall allow tracking of major weapon components (e.g., tube, breech block, breech ring) with fields for serial number, install date, and configuration changes. Provides traceability and auditability for configuration changes and maintenance history. Users can log new components, track EFC baselines, and deactivate prior configurations.

REQ-004 - Charge and Round Entry with EFC Calculation. ELMS shall allow entry of charge and round types to automatically calculate Equivalent Full Charges (EFC) and update total EFC per component. Standardizes performance tracking and avoids manual errors in EFC computation. System auto-calculates EFC and updates roll-up fields upon entry of round count and charge type.

REQ-005 - Role-Based Access Control for Data Integrity. ELMS shall implement role-based access control for the EWRB functionality, including read, write, and update privileges aligned to user responsibilities (e.g., Maintenance Clerk, Officer). Ensures least privilege and protects data integrity in serialized weapon records. Users can only perform functions (view, edit, update) permitted by their assigned roles.

REQ-006 - Audit Trail and Administrative Overrides. ELMS shall provide an administrative override function for manual EFC entry and require justification comments for audit traceability. Supports rebaselining and audit compliance when non-standard updates are required. Administrative EFC updates prompt for reason code and are logged with timestamp and user ID.

REQ-007 - Inspection and Technical Measurement Fields. ELMS shall support data entry for maintenance metrics such as pullover gage readings, elevation/cant/azimuth, and borescope inspections. Captures critical maintenance data used to assess weapon condition and performance. Users can input and update required inspection metrics with validation and summary roll-up.

REQ-008 - Reporting and Data Export Capabilities. ELMS shall support advanced search and export functionality for EWRB records, including filters by SN, EFC %, inspection date, and other metrics. Enables strategic and tactical reporting for sustainment planning and audit readiness. Users can generate reports and export to Excel-compatible formats with full field sets and filters.

REQ-009 - Document Attachment and Multimedia Upload Capability. ELMS shall allow users to attach multimedia files (e.g., images, PDFs, inspection reports, modification instructions) to specific weapon or component records. Enhances record completeness, enables visual and documentation-based validation, and supports audit and technical inspection requirements. Users can upload and view attachments associated with weapon records and all attachments are stored and retrievable per record.

REQ-010 - Disconnected Field Data Entry and Sync Capability. ELMS shall support offline (disconnected) data entry for EWRB functionality, with synchronization to the central system upon reconnection to MCEN. Supports continued operations in field environments with limited or no connectivity, ensuring timely data capture and delayed sync. Users can enter and save EWRB data offline and synchronize it with the main system once a secure network connection is restored.
