Which of the following is NOT a feature of the Defense Travel System?

The Defense Travel System (DTS) is specifically designed to support military and government travel. It facilitates various aspects of the travel process, including streamlining travel arrangements, automating travel reimbursements, and assisting with travel authorization processing. However, it does not include features for personal vacation planning. The primary focus of DTS is to ensure that official travel is managed efficiently within the framework of government policies and regulations, making it a tool solely for official travel needs rather than personal travel or vacation arrangements.
