How we write these guides

Useful answers, with the rules attached.

We build TDY Slayer to help military travelers organize their receipts and prepare DTS vouchers. These guides work alongside the app, with original examples and direct links to the Joint Travel Regulations and DTMO instructions.

Each guide shows when its sources were checked. We distinguish common rules from exceptions and explain when your Authorizing Official or travel office needs to make the decision. TDY Slayer is independent of DTS and the government.
