On Saturday, we learned of a deadly attack on American Green Berets by a member of the Afghan National Police. The Green Berets were from the 3rd Battalion of the 7th Special Forces Group (7th SFG) and were on an operation with their counterpart Afghan Special Operations Forces (ANSOF), conducting Key Leader Engagement (KLE). When the unit had finished their meeting, they moved to a field where they were awaiting pickup, when an Afghan policeman, firing a heavy machine gun, ambushed them. 

Two Americans, one Green Beret, and one SOT-A member were killed. Six Americans were wounded. At least eight of the Afghan SF troops were killed. Of the eight wounded Americans, two are in serious condition, one with a bullet wound to the face and the other with a wound in the chest. The others suffered bullet wounds to the legs. 

This latest incident took place in the Sherzad district of Nangarhar Province, which is located in eastern Afghanistan.

These so-called “Green-on-Blue” attacks are hardly rare and are once again growing in frequency. In the early days of the war in Afghanistan, these attacks were very rare. But in 2011, the number of such attacks rose sharply with 16 attacks on American or coalition personnel resulting in 35 KIA and 34 WIA. 

These insider attacks reached a high point in 2012 with 44 attacks on coalition troops resulting in 61 KIA and 81 WIA. In 2012, 15 percent of all of the coalition troops killed in Afghanistan were killed in Green on Blue attacks. 

In 2013, the numbers were still high but showed a decrease with 13 attacks on coalition troops. In these 14 troops were KIA with 29 WIA. As the years passed, the number of attacks dwindled significantly down to reaching just one such attack in 2017. But the numbers have been increasing again.

What’s the main motivation behind these attacks? It is difficult to say since different attackers have different motives. The Taliban claim that every Green on Blue attack is from an insider that they infiltrated into either the Afghan National Army or the police. While the U.S.-led coalition increased the vetting and training of Afghan units to minimize these attacks, there seems to be an uptick in them again as the United States is looking to negotiate an end to the 18-year war that began shortly after 9-11.
