DTS Oversight

What DTS Holds

The Defense Travel System is the system of record for TDY authorizations and vouchers across DoD. For Marines.

• DTS profile per Marine.
• Routing list assignments (group routing).
• Authorizations (the trip plan and approval).
• Vouchers (the post-trip claim).
• Trip history.
• Split disbursement settings.

The unit Defense Travel Administrator (DTA) owns the system administration. The leader owns the section's discipline within it.

Profile Setup Verification

Every Marine in the section needs an active DTS profile before the first TAD. New check-ins often arrive without a profile or with a stale profile from the prior unit.

Verify within the first 30 days at the section.

• Profile exists and is unlocked.
• Personal information current (name, EDIPI, rank).
• GTCC linked correctly.
• Bank account on file for split disbursement.
• Routing list assignment correct for the section.

A Marine assigned a TAD before profile verification produces a chain of errors at authorization.

Group Routing Assignments

DTS routes authorizations through a routing list. The list defines who reviews and who approves.

• Reviewer. Typically a SNCO or NCOIC who reviews the authorization for accuracy.
• AO (Approving Officer). Typically an officer or SNCO with delegated authority.
• DTA. Backstop for routing and system errors.

Verify each Marine sits in the correct routing list. A wrong list means the authorization sits in another section's queue.

Authorization Defaults

Common authorization defaults to verify on every Marine's profile.

• Default per diem. Set to standard CONUS or location-specific OCONUS.
• Default lodging. Marine Corps official lodging (Marine Lodges or Inns of the Corps) when the TAD destination is a Marine Corps installation, per MARADMIN 234/26MARADMIN 234/26 effective 25 May 2026. POC lodging if applicable. Otherwise commercial within the locality cap.
• Default transportation. POV mileage versus commercial air based on trip pattern.
• Default meal entitlement. Standard or proportional.

A Marine with old defaults from a prior unit produces authorizations that need manual correction every trip.

Common DTS Rejection Patterns

The AO returns authorizations and vouchers for specific reasons. Walk the section through the patterns.

Weekly Section DTS Review

Pull section DTS status weekly.

• Unsubmitted authorizations approaching trip dates.
• Submitted authorizations sitting at AO past 7 days.
• Unsubmitted vouchers past return date by 5 working days.
• Returned authorizations with no resubmission.

A 30-minute weekly review catches problems before deadlines lapse.

Reserve Component DTS Idiosyncrasies

Reserve Marines drilling at the unit hit DTS for IDT travel and AT travel. Some considerations.

• IDT travel reimbursement runs through DTS or alternative claim systems depending on the unit.
• AT travel typically routes through DTS.
• Reserve profiles often need refresh after status changes.
• Reserve Marines may have civilian-side travel programs in parallel that complicate the section view.

Coordinate with the unit DTA on reserve-specific routing.

When the Marine's Profile Is Locked

Common cause. GTCC delinquency or password expiration.

• Coordinate with DTA for unlock procedure.
• Address the root cause (GTCC payment, password reset).
• Verify alternate payment if TAD trip is imminent.

DTS Check-Out at PCS

When a Marine PCSes out of the section, coordinate DTS check-out with the unit DTA. The Marine cannot have unsettled DTS debt at transfer.

• Pull the Marine's DTS history before sign-out.
• Verify all vouchers settled.
• Verify GTCC paid down.
• Verify split disbursement landed correctly on each settled voucher.
• Coordinate any open dispute resolution before departure.
• DTA processes the formal DTS check-out.

A Marine who PCSes with unsettled DTS debt carries it to the gaining unit. The losing unit's section leader owns the closeout discipline.

Coordinating With the DTA

The unit DTA owns system administration. The leader walks Marines into trouble by adjusting authorization manually instead of routing through DTA for system fixes.

When to engage DTA.

• New Marine without profile.
• Profile lock or password issue.
• Routing list update needed.
• System error during authorization or voucher submission.
• Bulk action across multiple Marines (e.g., section-wide AO change after PCS).

Common DTS Oversight Failures

• Profile verification skipped at check-in.
• Routing list not updated after AO PCSes out.
• Defaults stale from prior unit.
• Weekly review never run, problems surface at trip dates.
• Marine adjusts authorization manually instead of DTA fix.

Where to Go Next

• TAD coaching for the trip-cycle context.
• Voucher audit for the pre-AO check.
• AO role for SNCOs and officers in the approval seat.
• GTCC during travel for the card-side discipline.
