To fill out the form correctly, start at Section I on page 1 and work through each section in order. Use a pen with permanent ink. Make any corrections with a single line strikethrough followed by your initials. Whiteout is not accepted on official military forms.
Section I: Personal and Assignment Information
Enter your full legal name, Social Security Number, current grade or rank, job title, and permanent duty station address. Civilian DoD employees should also include their organization code and pay grade. Accurate information here prevents processing delays at your travel office.
Section II: TDY Purpose and Travel Itinerary
Describe the official purpose of your TDY in clear, specific language. List each leg of travel with the departure point, destination, dates, and transportation mode. Accepted modes include personally owned vehicle (POV), government vehicle, rental car, and commercial air. Attach a conference invitation or official orders if your command requires them.
Section III: Per Diem and Cost Estimates
Look up the current per diem rate for your destination using the Joint Travel Regulations or the GSA per diem database. Record the daily lodging rate, the meal and incidental expenses (M&IE) rate, and any authorized reductions. Multiply the daily total by the number of travel days to get the estimated per diem. Add other authorized costs in the appropriate rows, including registration fees and local transportation expenses.
Signatures and Submission
The travel-requesting official (typically your direct supervisor) must sign first. The approving authority signs second to confirm the travel is authorized and within budget. Submit the signed form to your unit travel office or Defense Travel System (DTS) administrator before your departure date.
