It's a Typo. Other articles have identified him as a "Senior Airman"

A "Senior Airman" is what we used to call a Buck Sgt, but they don't
allow Buck Sgt's anymore, and an NCO is now a trained leader, and
usually on his/her second enlistment.

Typo's are quite common in newspapers, and doubly-so in the Internet
versions.

Paragraph extracted from a "Washington Post" article headlined 'Military
looking at Guantanamo security breaches' published in today's Colorado
Springs "Gazette".

Marine Gen. Peter Pace, vice chairman of the Joint Chiefs of Staff,
suggested Wednesday the investigation has been expanded beyond the
espionage-related arrests of Army Capt. James "Yousef" Yee, an Islamic
cleric at Guantanamo Bay, and Air Force Special Airman Ahmad al-Halabi, an
Arabic translator at the prison.

I have been out of the USAF for a lot of years but really try to keep up but
can any current member explain to me just what an Air Force Special Airman
is and what makes them special?
