Guard and Reserve TDY has gotten complicated with all the orders authority distinctions, DTS access gaps, and reimbursement timeline differences flying around. As someone who assumed reserve TDY entitlements were reduced compared to active duty — and was wrong in both directions on different occasions — I learned exactly where the rules are the same and where they genuinely differ. Today I will share it all with you.

Guard and Reserve TDY Is Different From Active Duty
Reserve component members — National Guard and Reserve — perform TDY under authorities and funding sources that differ from active duty in ways that affect entitlements, DTS access, and reimbursement timelines. The differences aren’t always obvious, particularly to members who work alongside active duty counterparts doing the same job and expect identical travel treatment.
Orders Authority and Funding
Reserve TDY travel must be performed under appropriate orders — Title 10 or Title 32, depending on the mission and activating authority. The funding line attached to the orders determines which DTS Organization and Routing Official has authority to approve the trip. A reserve member performing weekend drill doesn’t get DTS travel authorization; a member on orders for annual training, a special mission, or an activation does.
That’s what makes the orders authority question endearing to Reserve finance personnel — the entire entitlement structure flows from the orders document, and orders without the right authority create reimbursement problems that can take months to unwind.
Per Diem Entitlements for Reserve TDY
Reserve members performing TDY under orders receive the same per diem rates as active duty for the same TDY location. The M&IE structure, lodging reimbursement rules, and provided meal deduction requirements are identical under the JTR. What differs is the orders authority and the applicable fiscal year appropriation, not the day-to-day travel entitlement calculations.
I’m apparently someone who assumed reserve TDY entitlements were reduced compared to active duty — I was wrong in both directions on different occasions. The travel entitlements under proper orders are the same; the complexity is in the orders and funding documentation.
DTS Access for Reserve Members
Reserve members don’t always have standing DTS access between activations. Access is typically granted by the unit’s DTS administrator when orders are issued and may need to be reactivated if there’s been a gap since the last activation. Check access status at the time orders are issued rather than the night before departure.
Reimbursement Timelines
Probably should have led with this: reserve TDY voucher processing can take longer than active duty processing because the approving official may be a part-time staff member in the same Reserve unit, not a full-time finance office. Build that timeline into your personal cash flow planning — you may be personally carrying travel expenses for several weeks after a Reserve TDY before reimbursement arrives. Split disbursement to your GTC is even more important in this context.
