What type of orders detail the daily per diem a traveler should receive?

The type of orders that detail the daily per diem a traveler should receive are known as CED orders. CED stands for Commander's Expense Directive, which outlines the specific allowances and per diem rates for travel. These orders serve as an official guideline for what travelers can expect to receive in terms of expenses while on official travel, ensuring consistency and compliance with government regulations. They specify daily rates that cover meals, lodging, and other incidental expenses, providing clarity for both the traveler and the approving authorities regarding reimbursement.

Other options do not directly pertain to per diem rates. Authorization orders typically grant approval for travel but do not specify monetary amounts. Travel requests are formal submissions to seek permission for travel, and expense reports are submitted after travel to account for expenditures incurred, rather than outlining per diem details. Hence, CED orders are the specific documents that provide the daily per diem information for travelers.
