Its considered AWOL and punished by jail time. Technically, the maximum U.S. penalty for desertion in wartime remains death, although it hasn't happened since 1945. No US serviceman has received more than 18 months imprisonment for desertion or missing movement during the Iraq war. You will either get nonjudicial punishment or court martial.
It is technically a legal document, and it is binding. Which makes it unique from other types of documents. I’m not sure what you mean in regards to “tool”. But I would think it would be considered a reference document
They made federal government too weak.
Hope this helps!
