What is TDY?

The U.S. Military has three primary types of military orders:

  • Permanent Change of Station (PCS)
  • Temporary Duty (TDY)
  • Deployments Orders

It is important to keep in mind that the three types of military orders are not the same with each having its own characteristics.

Your military orders may affect how long you serve at the post, the specific location, and special duty pay.

Temporary Duty (TDY) is defined by the Department of Defense as:

Duty at one or more locations, away from the permanent duty station (PDS), under an order, providing for further assignment or pending further assignment, to return to the old PDS or to proceed to a new PDS.

Military branches under the U.S. Armed Forces have different references for Military TDY, like TAD (temporary additional duty) or TCS (temporary change of station).

However, they all mean basically the same thing that your military orders are temporary.

The primary difference between Military TDY and other orders is that it granted authorization for a service member to perform work away from the permanent duty station.

The Department of Defense requires the label Military TDY (or one of its variants) to approve travel pay, per diem, and coverage of other expenses to assist the soldier.

Since the assignment is temporary the service member can expect a shorter stay than a permanent station assignment, however, the length of the orders may vary.

The individual details of TDY orders are fleshed out with each commitment.

The specifics of your Military TDY outline expected duration, amount of travel pay, coverage of expenses, housing and food support, transportation, and other forms of assistance.

How long is a TDY?

Military TDY is temporary for military orders so the length is generally not longer than 180 days.

Temporary duty orders may range anywhere from a few days to a half year.

Long-term TDY is any orders which exist for longer than 30 days.

The Department of Defense provides a flat-rate per diem of 75 percent for any long-term TDY from 31 to 180 days.

Any long-term TDY which lasts longer than 180 days requires a flat-rate per diem of 55 percent.

Military TDY is a stark contrast from Permanent Duty Assignments and Deployments which have commitments of several months or years.

The Department of Defense authorizes TDY through Joint Travel Regulations.

Is TDY considered a deployment?

Technically there is a difference between a temporary duty assignment (TDY) and Deployment even though they are both military orders.

Deployments are similar to military TDY except for the member of deployment get assigned to a specific operation.

Therefore, deployments usually exist more to combat operations that take place overseas.

When most civilians think of military orders they commonly associate everything with being deployed, though that’s not always the case based on the actual military definition.

Deployment refers to assigning military personnel (generally but not always soldiers) from a home station to somewhere outside the continental United States.

Mobilizations also get classified as deployments under the Department of Defense guidelines.

How does a TDY differ from a deployment?

The biggest difference between deployment and temporary duty assignments is the length of the orders.

Military TDY is short-term with even the longer stints requiring less than a half year of commitment.

On the other hand, deployments are usually longer but not always and involve assignments outside the United States.

Additionally, deployments involve assignments to specific operations and usually in combat situations.

However, both types of military orders also have similarities.

For example, military personnel must leave their home station for a foreign place under each type of orders.

Military TDY is not always as serious as deployments.

For instance, a temporary duty assignment could mean nothing more than attending school, conferences, or a military-sponsored event.

Or it could pertain to a regular part of military duty where frequent travel is mandatory and the service member hopes to receive some form of compensation for their travels.

There are cases where military personnel earn TDY status even when working in the same geographic area as the home base to justify lodging and meal expenses associated with the duty.

Soldiers also rely on military TDY for house hunting and other searches when considering a new permanent change of station or outprocessing from military service.

One of the many perks of temporary duty assignments is that you can bring along the family.

The same is not true of deployments where it would put your spouse or other family members in danger.

Therefore, you not only can bring along a spouse for your temporary duty assignment but should welcome the opportunity.

Military personnel often spend months away from family and friends, so having a unique opportunity like this to catch up with a loved one is rare and special.

MilitaryShoppers.com put together a great resource on the topic.

It explains the pros and cons of tagging along with a significant other while he or she is on TDY.

The most important thing to keep in mind is that while you can live with your spouse while on temporary duty assignment his or her time is still limited and it might drain your budget quickly.

Other than that it’s an enticing opportunity to catch up after potentially months of separation.

Will I get paid extra during a TDY?

Despite having to leave your home station there is nothing more rewarding than a little extra pay in freedom.

It is exactly what temporary duty assignments provide to service members.

In fact, the reason that military personnel may request or seek TDY is the opportunity to put more in the wallet.

Military TDY usually grants per diem pay which helps cover lodging, meals, and incidental expenses.

You get per diem pay regardless of what you spend each day on daily expenses.

As a result, if you budget accordingly you can earn extra cash by pocketing whatever per diem you don’t spend on daily living expenses.

What kind of accommodations can I expect during a TDY?

The accommodations of temporary duty assignments are nothing to brag about yet offer incentives that most military personnel don’t get to enjoy.

For example, the opportunity to take your significant other along with TDY is a major advantage for some over deployments.

Military personnel may get the opportunity to stay at furnished apartments or long-term stay hotels.

Long-term stays help save you money on your per diem since you can cook your own meals as opposed to dining out all of the time.

Furnished apartments may also include laundry and other housing services to save even more money.

Service members on TDY may also request a cash advance of 60-80% of the total value.

It helps cover move-in costs as opposed to spending out of their own pocket.

Some military organizations deem anything over 30-45 days long-term TDA.

For this reason, it allows partial reimbursement on living expenses prior to concluding the assignment.

Conclusion

Military TDY, or temporary duty assignments, refer to relatively short term military orders away from a home station.

Temporary duty assignments range from a couple of days to under a half-year of service.

Military TDY is a good thing for soldiers despite the travel arrangements, as it helps cover lodging, food, and transportation regarding the orders.
