Nomad Shadow

Operation Nomad Shadow is the name of a classified United States military operation that may have begun in November 2007 to share intelligence information between the U.S. and the Republic of Turkey. The operation may involve only a few dozen American servicemembers at any one time plus an unknown number of Turkish officials. A U.S. military-affiliated newspaper claimed the operation "reportedly provided Turkey with intelligence on Kurdish separatists ahead of Turkey’s incursion into northern Iraq in December 2007."

U.S. servicemembers who deploy in support of Operation Nomad Shadow may also be concurrently attached to support Operation Iraqi Freedom.

In 2013 the PKK claimed to have shot down an American drone patrolling the Turkey/Iraq border as part of the program.
