Sponsor Responsibilities and Completion - S-1 Procedural Page

Role and responsibility

The assigned sponsor owns inbound outreach, arrival support, and orientation per MCO 1320.11HMCO 1320.11H paragraph 4.b.(8) (Assigned Sponsors). The SC briefs the sponsor on responsibilities per paragraph 4.b.(7) and runs the Privacy Act brief per paragraph 5.c. The S-1 officer signs by direction on the Page 11 documenting sponsorship completion per MCO P1070.12KMCO P1070.12K Chapter 6. The inbound Marine confirms sponsor execution at the inbound brief.

Source documents flow from the Sponsorship Assignment Letter per Enclosure (7), the matching Welcome Aboard Letter per Enclosure (4), (5), or (6), the sponsor responsibility brief content, the Privacy Act brief, the inbound brief attendance, and the inbound Marine's acknowledgment of sponsor execution. Sponsor outputs include the executed milestone schedule, the contact log, the IR&R handoff record per paragraph 4.b.(9), the inbound brief Page 11 per MCO P1070.12K paragraph 4006, and the unit sponsorship roster entry showing completion.

Per MCO 1320.11H paragraph 4.b.(8), the sponsor reaches out to the inbound Marine before arrival, sends the welcome aboard letter, provides arrival support, escorts the Marine to required check-ins, and orients the Marine to the unit. The sponsor coordinates installation IR&R handoff for inbound family per paragraph 4.b.(9).

Trigger events

• Sponsorship assignment letter signed per Enclosure (7).
• Inbound Marine reaches initial outreach milestone.
• Welcome aboard letter delivery due.
• Inbound Marine arrival imminent.
• Arrival logistics coordination opens.
• Required check-ins schedule (S-1, medical, dental, security, supply).

Processing workflow

1. Acknowledge the sponsorship assignment. Per MCO 1320.11HMCO 1320.11H Enclosure (7), the sponsor acknowledges receipt of the assignment letter.
2. Complete the sponsor responsibility brief. Per paragraph 4.b.(7), the SC briefs the sponsor on responsibilities, the milestone schedule, the welcome aboard letter type, the Privacy Act framework, and the IR&R handoff.
3. Execute initial outreach. Per paragraph 4.b.(8), the sponsor reaches the inbound Marine soon after assignment with a personal contact (email, message, or call).
4. Send the welcome aboard letter. Per Enclosures (4) for CONUS, (5) for Accompanied OCONUS, or (6) for Unaccompanied OCONUS, the sponsor sends the matching letter.
5. Maintain pre-arrival contact. The sponsor follows up through PCS execution on housing, transportation, and arrival logistics.
6. Coordinate arrival logistics. The sponsor coordinates pickup (when applicable), initial billeting, and unit orientation.
7. Escort the inbound to required check-ins. The sponsor escorts or supports the Marine through S-1, medical, dental, security, and supply check-ins.
8. Coordinate IR&R Program Manager handoff. Per paragraph 4.b.(9), the sponsor coordinates the IR&R handoff for inbound family.
9. Confirm execution at the inbound brief. The Marine acknowledges sponsor execution.
10. Cut Page 11 documenting sponsorship completion. Per MCO P1070.12KMCO P1070.12K Chapter 6, document the sponsorship participation in the inbound brief Page 11.

Systems of record and forms

Systems

• MCTFS. Holds the inbound Marine record.
• MOL. Surfaces sponsor information.
• Unit Sponsorship Roster. Tracks completion.
• OMPF Field Folder. Stages the inbound brief Page 11.

Forms

• Sponsorship Assignment Letter. Per Enclosure (7).
• Sponsor Welcome Aboard Letter (CONUS, Accompanied OCONUS, Unaccompanied OCONUS). Per Enclosures (4), (5), (6).
• Sponsor Contact Log. Local format documenting outreach milestones.
• Inbound Brief Page 11. Per MCO P1070.12K paragraph 4006 (NAVMC 118 (11) Administrative Remarks).
• Sponsor Execution Acknowledgment. Local format signed by the inbound Marine.

Common pitfalls

• Initial outreach delayed. Per MCO 1320.11HMCO 1320.11H paragraph 4.b.(8), initial outreach runs soon after assignment. A delayed outreach loses the inbound Marine's trust.
• Privacy Act breach. Per paragraph 5.c, 5 USC 552a5 USC 552a, and SECNAVINST 5211.5FSECNAVINST 5211.5F paragraph 7 (Privacy Act), the sponsor handles inbound PII per the privacy rules. Personal email to non-Marine Corps addresses is not approved for PII.
• Welcome aboard letter type mismatched. Per Enclosures (4)-(6), the assignment type drives. Validate at the welcome aboard letter draft.
• Required check-in escort skipped. The Marine arrives unfamiliar with the unit. The sponsor escorts per paragraph 4.b.(8).
• Inbound brief Page 11 omitted. The OMPF lands without record. Cut the Page 11 at the inbound brief per MCO P1070.12KMCO P1070.12K Chapter 6.

Decision points

• Sponsor execution gap. The sponsor cannot execute (deployment, schedule conflict). The SC reassigns per paragraph 4.b.(7). The new sponsor receives a fresh Enclosure (7) letter.
• IR&R handoff scope. Per MCO 1320.11HMCO 1320.11H paragraph 4.b.(9), the IR&R handoff applies to inbound family. Single inbound Marines coordinate as needed for in-and-out processing.
• Inbound brief Page 11 wording. Per MCO P1070.12KMCO P1070.12K Chapter 6, the Page 11 documents the brief. Standard wording references sponsor execution and inbound brief attendance.
