Joining a Unit (Inbound Reporting and Check-In)

Start Here If You Are New to Joining a Unit

Joining a Unit is the closeout step of every PCS. You finish travel, you report to the new permanent duty station (PDS), the new command endorses your orders, and you start in-processing. The reporting endorsement closes the PCS travel period and opens the inbound check-in window. Inside the first 24 hours, 72 hours, 7 days, and 30 days you complete sequenced stops that confirm your pay, records, medical, dental, family enrollment, and operational placement. The Sponsorship Program connects you with a sponsor before arrival. Initial counseling within 30 days locks in performance expectations. PCS pay actions (BAH start, travel voucher within 5 working days, DLA, TLE) flow through S-1 once you report. Per MCO 1300.8MCO 1300.8, MCO 1000.6MCO 1000.6, MCO 1320.11HMCO 1320.11H, MCO 1610.7MCO 1610.7, and JTR Chapter 5.

Before You Arrive

The work to join a unit starts before the new PDS gate.

Marine Corps Sponsorship Program (MCO 1320.11H)

Per MCO 1320.11HMCO 1320.11H, the gaining unit assigns a sponsor to every inbound Marine. The sponsor.

• Contacts the inbound Marine within 10 working days of receipt of the gaining unit's notification.
• Provides a welcome aboard package and installation information.
• Coordinates lodging, school enrollment, and family logistics if requested.
• Meets the Marine on arrival or at the first reporting stop.

If you have not heard from a sponsor 30 days before report date, contact the gaining unit S-1 directly. Request the sponsor assignment.

Pre-Arrival Contact With S-1

Call or email the gaining unit S-1 before you arrive. Confirm.

• Report date and reporting location (which building, which deck, which office).
• Required documents to bring to check-in.
• Local lodging arrangements (TLE eligibility, on-base lodging availability).
• DEERS update timing for dependents.
• School liaison contact for school-age dependents.

Documents to Bring to Reporting

• PCS orders (all pages, including endorsements and modifications).
• NAVMC 118NAVMC 118-3 leave document showing PCS leave taken.
• Travel itinerary and receipts (flights, lodging, rental car, fuel for POV).

Reporting at the New PDS

Report Date and Time

Per MCO 1300.8MCO 1300.8 and JTR Chapter 5, the report date is the date specified on the PCS orders. The Marine reports on or before that date.

The travel time and PCS leave granted on the orders determine the report date. The reporting endorsement closes the PCS travel period.

Where to Report

The PCS orders identify the reporting location. Common reporting points.

• The gaining unit S-1 (Personnel/Admin Office).
• The Battalion or Squadron Adjutant.
• The Receiving and Holding Section at major installations.
• A specific NCOIC or SNCOIC named in the orders.

If the report date falls on a weekend or holiday, report on the next working day unless the orders direct otherwise.

Reporting Endorsement

The reporting endorsement is added to the PCS orders by the gaining S-1 or the designated reporting authority. The endorsement.

• Confirms the date and time of report.
• Captures any deviation from the originally scheduled report date.
• Closes the PCS travel period for pay and entitlement purposes.
• Triggers the BAH start at the new PDS rate.

The Marine retains a copy of the endorsed orders. The endorsed orders attach to the DTS travel voucher.

Late Reporting

Per MCO 1300.8MCO 1300.8, late reporting without authorization is misconduct. The Marine notifies the gaining unit S-1 immediately if reporting will be delayed for any reason (mechanical breakdown, illness, weather). The gaining unit may grant a delay or initiate UCMJ action depending on the circumstances.

Reporting Off PCS Leave

Marines on authorized PCS leave report at the end of leave per MCO 1050.3JMCO 1050.3J. Leave is computed in the orders. The reporting endorsement reflects the end of leave plus authorized travel time.

Post-PCS Pay Actions

TLE Submission Window

If the Marine took TLE at the new PDS while waiting for permanent housing, submit through DTS. The Temporary Lodging Expense page covers TLE.

Dependent Travel Voucher

If dependents traveled separately (deferred travel, EBV, or non-concurrent travel), submit a separate dependent travel voucher per the Member and Dependent Travel page.

First 30 to 90 Days

Beyond the initial check-in window, the Marine integrates into the unit.

30-Day Counseling Acknowledgment

The Marine confirms in writing that initial counseling occurred. Disputes about performance expectations are documented at this stage.

Permanent Section Assignment

The S-3 finalizes the Marine's permanent section, billet, and duty assignment. The Marine moves out of the temporary holding pool if applicable.

Permanent Housing

Marines with dependents typically move from TLE lodging to permanent housing within the 14-day TLE window. Family housing wait lists or off-base lease execution drives this timing.

MOS Skill Sustainment

The Marine begins MOS-specific training, certifications, or qualification sustainment per the unit's training plan.

90-Day Counseling

Per MCO 1610.7MCO 1610.7, midpoint counseling at the 90-day mark documents performance trends and adjusts expectations as needed.

Common Reporting Issues

Missing Reporting Endorsement

If the Marine did not receive a reporting endorsement at the original reporting stop, return to S-1 with the orders. The endorsement is required before pay actions process.

Late Reporting Due to Travel Disruption

Mechanical breakdown, weather, or commercial transportation delays. The Marine notifies the gaining S-1 immediately. Documentation (mechanic invoice, weather advisory, airline cancellation) supports a justified late report.

BAH Did Not Start at New Rate

The Marine verifies the reporting endorsement was processed in MCTFS. If MCTFS shows the old PDS rate, S-1 submits a pay correction.

DEERS Mismatch

If DEERS shows the wrong address or unit, the Marine updates through the ID card office or via milConnect (https://milconnect.dmdc.osd.mil/). DEERS errors block Tricare enrollment and can stop family pay entitlements.

Sponsor Did Not Make Contact

The Marine reports to S-1 directly. The S-1 documents the sponsorship lapse. The Marine still receives all check-in support without a sponsor.

OMPF Shows Wrong Unit

If MOL or OMPF still shows the prior unit after 7 days, the Marine works with S-1 to confirm the assignment record was updated. MMEA monitors may need to push the assignment update.

Common Questions Marines Ask

When does my BAH start at the new rate?

Per FMR Volume 7A Chapter 26, BAH at the new PDS rate starts the day after the reporting endorsement. Verify on the next LES.

How fast do I have to submit the PCS travel voucher?

Per JTR Chapter 5, within 5 working days of arrival at the new PDS. Submit through DTS with all receipts.

What if my sponsor never contacted me?

Report to the gaining unit S-1 directly. Sponsorship is a command responsibility per MCO 1320.11HMCO 1320.11H but the lack of a sponsor does NOT relieve you of the duty to report on time. The S-1 supports all inbound Marines regardless of sponsorship status.

When does initial counseling happen?

Within 30 days of reporting per MCO 1610.7MCO 1610.7. The reporting senior conducts the counseling and the Marine acknowledges in writing.

What documents do I need to bring to S-1 on day one?

PCS orders (all pages and endorsements), leave documents, travel receipts, marriage and birth certificates for DEERS updates, and any hand-carried medical or dental records.

What is the difference between reporting endorsement and check-in?

The reporting endorsement is the formal note on the orders confirming you arrived. Check-in is the multi-stop process (S-1, medical, dental, S-4, S-3) that follows. The endorsement happens on day one. Check-in extends across the first 30 days.

When can I move out of TLE into permanent housing?

As soon as housing is available. TLE caps at 14 days for CONUS (per current JTR, with a forthcoming 21-day expansion per MARADMIN 573/24MARADMIN 573/24). Plan your housing search to fit the window.

What if I report late due to weather or mechanical breakdown?

Notify the gaining unit S-1 immediately. Document the cause (weather advisory, mechanic invoice, airline cancellation). Justified late reports do not result in disciplinary action.

How does the Family Care Plan apply at the new unit?

Single Marines with dependents and dual-military couples submit the updated Family Care Plan to the new command within 30 days. The new command verifies the plan covers the local AO.
