Select the non-mileage expense that requires a receipt in accordance with the JTR and the DoD FMR?

According to the Joint Travel Regulations (JTR) and the Department of Defense Financial Management Regulation (DoD FMR), lodging expenses require a receipt for reimbursement. This applies to any overnight accommodations incurred during official travel. The receipt must clearly show the dates of stay, the name and location of the lodging, and the amount paid. Other non-mileage expenses, such as meals, may not require receipts if they fall within certain per diem allowances.
