The BCIS has decided to discontinue the current RTD and reentry permit. In their place, there will be a document called " Travel Document Issued by the U.S. Department of Homeland Security, Bureau of Citizenship and Immigration Services." The sample I saw looks strikingly like the American passport, except for the green color. The BCIS claims that the document is very fraud-resistant.
On the inside page of the front cover the document will either say RTD or entry permit.
