As tensions with Iran remain high, the Pentagon and NATO have paused the training of Iraqi police and military units over concerns of insider attacks.

Military officials are concerned that fighters from the Popular Mobilization Units (PMUs), Shia militant groups and Iranian proxies, might have infiltrated the ranks of the Iraqi police and military. (Historically, green-on-blue attacks have been more common in Afghanistan.)

These concerns are fairly well-grounded. Shia Muslims are a majority in Iraq and they control much of the government, which, in turn, is under the influence of Tehran. Numerous American and NATO units in the country are housed or work on the same bases as the Iraqis.

Most of his equipment is American (he even sports the Punisher patch…). ISOF members have been operating alongside American Special Operations units in the fight against the Islamic State. The threat of an insider attack in one of the many American SOF elements in the country, which include Navy SEALs, Marine Raiders, and Green Berets, is high. 

“We continue to take all precautions necessary,” said NATO spokesman Dylan White in a statement. “NATO’s mission is continuing, but training activities are temporarily suspended.”

NATO’s presence in Iraq comes in the form of several hundreds of troops. Part of the NATO Mission Iraq (NMI), the troops are there to train, advise, and support the Iraqi military. Led by the Canadian Major General Jennie Carignan, NMI is comprised of troops from both NATO and non-NATO partner countries.

Concerns over insider attacks notwithstanding, most of the Iraqi police and military have been staunch partners in the fight against the Islamic State.
