The ongoing probe began two months ago, Chris Grey, a spokesman for the Army’s Criminal Investigation Division, told Fox News.
The suspects were part of a Arabic translation program called "09 Lima" and use Arabic as their first language, two sources told Fox News. Another military source said they were Muslim.
If I’m not mistaken the 09 Lima program is where the Army was actively recruiting Arabic speakers for service in the Army and that is their MOS. I think the soldier who is still (last I recall anyways and I can’t remember his name, but it was an Arab name) MIA in Iraq joined the Army under that program.
