Command Combat Casualty Operations Center - S-1 Procedural Page

Role and responsibility

The MEF and MEF MSE(s) maintain 24-hour casualty processing capability during combat operations or mass casualty events per MCO 3040.4MCO 3040.4 Chapter 2 paragraph 6. The G-1 officer at MEF level activates and runs the Combat Casualty Operations Center (CCOC). Subordinate S-1 sections feed casualty reports to the CCOC. The S-1 officer at the unit level processes unit-level casualty reports per the operational tempo.

Source documents flow from incident reports, PCRs from subordinate units, NCIS notifications, hospital reports, and the operational situation reporting cycle. CCOC actions land as roll-up casualty reports, surge CACO assignment coordination, and higher headquarters casualty posture briefs. Outputs include the consolidated MEF casualty roll-up, the CACO assignment surge log, the mass casualty incident response record, and the commander brief on casualty posture.

Per MCO 3040.4MCO 3040.4 Chapter 2 paragraph 6 (Command Combat Casualty Operations Center), during combat operations or a mass casualty event, the MEF and MEF MSE(s) maintain 24-hour capability to process casualty reports and assist with response operations.

Trigger events

• Combat operations activate the deployed unit casualty cycle.
• Mass casualty event triggers CCOC activation.
• Pre-deployment cycle approaches operational tempo requiring CCOC stand-up.
• HQMC Casualty Section coordinates with CCOC for theater-wide casualty management.
• Subordinate unit casualty surge triggers CCOC escalation.
• Operational tempo reduces and CCOC stands down.
• CCOC personnel rotation cycle.

Processing workflow

1. Establish 24-hour capability. Per MCO 3040.4MCO 3040.4 Chapter 2 paragraph 6, the MEF and MEF MSE(s) maintain the capability during qualifying operations.
2. Assign CCOC personnel. The G-1 officer designates CCOC watch officers, NCO watchstanders, and admin support per paragraph 6.
3. Train CCOC personnel. Run pre-deployment training on PCR processing under tempo, mass casualty procedures, and HQMC Casualty Section coordination.
4. Coordinate with HQMC Casualty Section. Establish coordination cycle and reporting routes.
5. Process casualty reports at tempo. Run PCR processing per the operational pace.
6. Coordinate mass casualty surge response. On mass casualty events, the CCOC surges to manage multiple simultaneous PCRs and CACO assignments.
7. Track casualty roll-up. Maintain the consolidated casualty roll-up for the MEF or MSE.
8. Coordinate CACO assignment surge. Mass casualty events require multiple simultaneous CACO assignments. The CCOC coordinates with HQMC Casualty Section.
9. Brief MEF commander. The G-1 officer briefs the MEF commander on casualty posture on a fixed cycle.
10. Stand down. On operational tempo reduction, the G-1 officer stands down the CCOC per the order rules.

Systems of record and forms

Systems

• CCOC watch log. Local log of casualty reports processed under operational tempo.
• DCIPS. National-level casualty processing roll-up.
• HQMC Casualty Section coordination. Theater-wide casualty management.
• MEF casualty roll-up report. Local consolidated MEF view.

Forms

• PCR (Personnel Casualty Report). Standard format under tempo.
• CCOC Watch Standing Schedule. Local format documenting 24-hour coverage.
• Mass Casualty Incident Response Plan. Local plan per operational requirement.
• Casualty Posture Brief Slides. Local brief format for MEF commander.

Common pitfalls

• 24-hour capability not maintained during qualifying operations. Per MCO 3040.4MCO 3040.4 Chapter 2 paragraph 6, the capability is required.
• CCOC personnel rotated without overlap training. The watch loses continuity. Run overlap shifts during rotation.
• HQMC Casualty Section coordination broken. The CCOC reports without theater-wide context. Maintain coordination cycle.
• Mass casualty surge response untested. The first mass casualty event finds the CCOC unrehearsed. Train pre-deployment per paragraph 6.
• Stand-down premature. CCOC stands down before operational tempo reduction is confirmed. Coordinate with the MEF commander.

Decision points

• CCOC activation threshold. Per MCO 3040.4MCO 3040.4 Chapter 2 paragraph 6, combat operations or mass casualty events trigger activation. The MEF G-1 officer assesses.
• Surge response scaling. Mass casualty events vary in scale. The G-1 officer scales the surge response per incident size.
• Stand-down timing. The G-1 officer assesses operational tempo reduction and coordinates stand-down with the MEF commander.
