Alien technologies officer

An alien technologies officer (sometimes nicknamed the A-T officer) is a billet in the Starfleet and other starfaring governments.

The billet is an interdisciplinary one, combining the aptitudes and interests of archaeologists, sociologists, art historians, engineers and linguists, among other specialties.

Alien technologies officers may be assigned to vessels of any size. They are often included in the crew of combat support tenders and other support craft.

In 2292, Peter Alderson was an alien technologies officer assigned to USS. (: "Belonging")

Background
I had never seen this billet used in any broadcast, pro fiction or fan fiction Trek prior to my using it in "Belonging". I interpreted the billet's duties from the unnamed Kzinti A-T officer in 's "The Warriors," the 1967 Known Space story that introduced the Kzinti.
