Deployments, Exercises, and Operations - S-1 Procedural Overview

Role and responsibility

The S-1 officer supports unit deployment readiness across the full deployment cycle per MCO 3000.13BMCO 3000.13B (Marine Corps Readiness Reporting), MCO 3000.18BMCO 3000.18B (FDP&E Manual), and MCO 3120.12AMCO 3120.12A (GFM and Force Synchronization). The S-1 chief tracks personnel readiness inputs to DRRS and supports the unit commander on personnel-driven readiness ratings. The DRRS administrator submits readiness reports per the published cadence. The IPAC supports personnel transactions during deployment cycles. The unit commander signs DRRS reports and the FDP&E sourcing inputs. HQMC PP&O sponsors the readiness reporting, deployment planning, and GFM frameworks. MARFOR commands coordinate sourcing.

Source documents flow from the unit Mission Essential Task List (METL), the T&R event status per MCO P3500.72A, the MCTFS personnel readiness data, the equipment readiness reports, the DRRS architecture per MCO 3000.13B and MARADMIN 518-21MARADMIN 518-21, the deployment planning inputs per MCO 3000.18B, the GFM tasking per MCO 3120.12A, the casualty reports during operations, and the individual augment taskings. Operations outputs include the submitted DRRS readiness reports, the FDP&E sourcing inputs, the executed deployment package, the in-stride T&R event certifications, the individual augment fills, the casualty reporting per MCO 3040.4, the redeployment and reset cycle records, and the post-deployment readiness reports.

Per MCO 3000.13B and DoDD 7730.65, Marine Corps units report readiness on the DRRS architecture covering Personnel (P), Supply (S), Equipment Condition (R), Training (T), and Equipment On-Hand (C) ratings. Per MARADMIN 518-21, DRRS-MC consolidates into DRRS. Per MCO 3000.18B (FDP&E Manual), force deployment planning runs through Time-Phased Force and Deployment Data (TPFDD) tied to Joint OPLANs and CJCSM 3122.01A JOPES procedures. Per MCO 3120.12A, GFM and Force Synchronization coordinate force sourcing across MARFORs.

Trigger events

• New OPLAN tasking arrives at the unit.
• DRRS reporting cycle opens.
• GFM tasking from MARFOR or HQMC.
• MEU certification cycle opens.
• Pre-deployment training cycle begins.
• Individual augment requirement received.
• Deployment date approaches triggering FDP&E sourcing.
• RIP/TOA with relieving unit.
• Redeployment and reset cycle initiates.
• Casualty during operations triggering MCO 3040.4 process.
• DRRS rating change triggers commander assessment.

Processing workflow

1. Support DRRS readiness reporting. Per MCO 3000.13BMCO 3000.13B, the unit reports readiness on the DRRS cycle. Per MARADMIN 518-21MARADMIN 518-21, DRRS-MC consolidates into DRRS.
2. Coordinate force deployment planning. Per MCO 3000.18BMCO 3000.18B, the FDP&E Manual sets the procedural framework. TPFDD development and JOPES interface support the deployment.
3. Support GFM tasking. Per MCO 3120.12AMCO 3120.12A, GFM and Force Synchronization run through MARFOR and HQMC PP&O.
4. Coordinate MAGTF and MEU operational personnel actions. Per MCTP 3-30GMCTP 3-30G, the S-1 supports MAGTF manpower and personnel administration.
5. Manage T&R event execution. Per MCO P3500.72A and the unit T&R event roadmap, the S-1 supports certification and reporting.
6. Process individual augmentation taskings. Per HQMC and MARFOR tasking, the S-1 sources individual augments. OSCAR (Operational Support Augmentation Requirement) and joint individual augmentee process drives the actions.
7. Support pre-deployment training. Per the deployment readiness check list, the unit completes pre-deployment training and certification ahead of deployment.
8. Coordinate redeployment and reset. After deployment, the unit completes redeployment processing and the reset cycle.
9. Maintain unit personnel readiness during deployment. The S-1 tracks casualties, replacements, and personnel transactions in the deployed environment.
10. Coordinate casualty reporting and replacement operations. Per MCO 3040.4 (Casualty Affairs cross-reference), casualty actions route per the casualty framework.

Systems of record and forms

• Marine Corps Total Force System (MCTFS). Personnel readiness data feed.
• Operational Support Augmentation Requirement (OSCAR) database. Per HQMC tasking.
• Global Force Management Allocation Plan (GFMAP). Per MCO 3120.12A.

• TPFDD Development Worksheet. Per MCO 3000.18B and JOPES.
• GFM Tasking Memorandum. Per MCO 3120.12A.
• Individual Augment Tasking Order. Per HQMC and MARFOR.
• Pre-Deployment Readiness Check List. Per the deployment cycle.
• RIP/TOA Memorandum. Per the deployed environment.
• Reset Cycle Memorandum. Per the redeployment process.

Common pitfalls

• DRRS rating reported without commander assessment. Per MCO 3000.13BMCO 3000.13B, the commander narrative supports the rating.
• TPFDD inputs late on FDP&E sourcing. Per MCO 3000.18BMCO 3000.18B, the sourcing timeline drives the TPFDD development.
• Individual augment tasking not coordinated through MARFOR. Per MCO 3120.12AMCO 3120.12A, GFM tasking coordinates through MARFOR.
• Pre-deployment training certification skipped. Per the deployment cycle and MCO P3500.72A, certification supports deployment readiness.
• Redeployment processing skipped. Per the reset cycle, processing supports unit refit.
• Personnel readiness inputs to DRRS not aligned with MCTFS. The S-1 reconciles MCTFS data with DRRS inputs.
• Casualty reporting during operations delayed. Per MCO 3040.4 cross-reference, casualty actions run on the 8-hour PCR timeline.
• MEU certification cycle inputs late. Per the MEU CompUTEx and SOC certification schedule, S-1 supports the cycle.

Decision points

• DRRS rating versus commander assessment. Per MCO 3000.13B, the data-driven rating combines with the commander's narrative assessment.
• TPFDD sequence. Per MCO 3000.18B and JOPES, the TPFDD sequence aligns with the Joint OPLAN time-phasing.
• Individual augment sourcing priority. Per MCO 3120.12A, the GFM priority drives sourcing.
• Pre-deployment training scope. Per MCO P3500.72A and the unit METL, the training scope addresses deployment-specific tasks.
• Casualty replacement priority. Per MCO 3040.4 and MCTP 3-30G, the casualty replacement process restores unit personnel readiness.
