Contact another Army office as soon as possible (not her office), and from there, find out who to contact on the matter at hand. Here are some possibilities. There should be an officer in charge of each civil service office. Find out how to contact him or her. Be sure to include the info/properties file from the PDF with the name (Natalie Abt, etc.) and the article and file posted to the Huffington Post.

For example, “Is Natalie Abt the spokesperson for the U.S. Army? Is she posing as spokeperson for the Army to the media?”
Yes, civil service—not an officer or enlisted person. There’s no rank shown for the person in documents, but one shows a “Ms.”
