Data last updated on June 17, 2017
Attacks on Coalition forces by Afghan forces — the so-called green-on-blue attacks — have emerged as a major threat in the 16-year-old war in Afghanistan. These attacks from within have increased dramatically between 2011 and 2013; in 2012 they accounted for 15% of Coalition deaths.
As the United States prepares to complete the withdrawal of its combat troops from Afghanistan by the end of 2016, the US military and its Coalition partners are increasingly shifting security responsibilities to Afghan forces. The success of this security transition depends greatly on the strength and competence of the Afghan military and police. Accordingly, the training of the newly-mustered Afghan forces has become a linchpin of Coalition strategy, which in turn hinges upon the work of trainers with Afghan security forces. This situation has placed Coalition troops at increasing risk as the drawdowns continue and Taliban efforts to infiltrate Afghan forces are being ramped up.
In 2012, attacks by Afghan forces on Coalition forces surged; in 2012, they accounted for 15% of Coalition deaths. In 2011, green-on-blue attacks accounted for 6%; in 2010, 2%; in 2009, 2%; and in 2008, less than 1%.
Although NATO commanders initially stated that an estimated 90% of the attacks are due to cultural differences and personal enmity, the attacks began spiking in 2011, just after President Barack Obama announced the plan to pull the surge forces, end combat operations in 2014, and shift security to Afghan forces. The Taliban also have claimed to have stepped up efforts at infiltrating the Afghan National Security Forces.
Disagreeing with NATO’s analysis, the Afghan government has blamed the problem on “infiltration by foreign spy agencies,” including those of “neighboring countries,” The Guardian reported. The Afghan government also predicted that vetting of recruits to the Afghan military and police would soon improve as the forces were reaching their target capacity after a rapid buildup.
While cultural and personal differences may play a role in the increase in attacks, Taliban infiltration and defections by Afghan security personnel who have decided to ingratiate themselves with the Taliban by attacking NATO forces likely play a far more significant role than NATO official admit. Without a complete study of the attacks, including those that do not result in casualties, it is impossible to have a full understanding as to what motivates Afghan security personnel to turn on their foreign partners.
In May 2012, ISAF commander General John Allen said that about half of the green-on-blue attacks have been carried out by Taliban infiltrators. In August, General Allen said that approximately 25% of the green-on-blue attacks were due to Taliban infiltration and/or coercion of Afghan forces, according to The New York Times. The Taliban routinely take credit for the attacks.
The US military became so concerned with the green-on-blue attacks in 2012 that it ordered units to designate “guardian angels” in each unit whose job is to provide security for troops working with Afghans. In mid-August, field commanders were told they can increase the number of “guardian angels” depending on the tactical situation, Reuters reported.
The surge in green-on-blue attacks prompted the US military to expand its counterintelligence capability in Afghanistan at the battalion level and above, according to Reuters. In addition, ISAF commander John Allen recently directed all US and NATO troops to carry a loaded weapon at all times, Fox News reported. Other measures taken include the adoption of an eight-step vetting process for recruits and revised NATO training requirements.
Announcing these changes, General Martin Dempsey, Chairman of the Joint Chiefs of Staff, said that Afghan forces were also trying to address the problem and had already discharged “hundreds of soldiers” suspected of having been radicalized. The Telegraph reported that the Afghan army has added 300 intelligence specialists to help detect infiltrators, and that 75 percent of the force will be reinvestigated and enrolled in a biometrics database.
Although as a matter of policy ISAF does not report on attacks that do not result in deaths, this trend seems to be changing, as two of the three attacks reported in July 2012 involved situations in which soldiers were wounded but not killed.
However, many insider attacks remain unreported. If an attack by Afghan personnel does not result in a death or injury, and it is not reported in the press, the Coalition will not release a statement on the incident.
ISAF told The Long War Journal in March 2012 that “these statistics,” the number of attacks that did not result in a casualty, are “classified.”
“[A]ttacks by ANSF on Coalition Forces … either resulting in non-injury, injury or death … these stats as a whole (the total # attacks) are what is classified and not releasable,” Lieutenant Colonel Jimmie Cummings, ISAF’s former Press Desk Chief, told The Long War Journal. Cummings said that ISAF is “looking to declassify this number.”
The overall number of these attacks remains classified to this day.
The Taliban have seized on the green-on-blue attacks in their propaganda, and routinely claim each attack to be a result of infiltration. In early August 2012, the Taliban released a video of two Afghan soldiers who attacked ISAF soldiers in Kunar and Uruzgan [see Threat Matrix report, Observations on Taliban video ‘welcoming’ rogue ANA soldiers].
Mullah Omar, the previous leader of the Islamic Emirate of Afghanistan, or the Taliban, addressed the issue of green-on-blue attacks in a statement released on Aug. 16, 2012. Omar claimed that the Taliban “cleverly infiltrated in the ranks of the enemy according to the plan given to them last year,” and urged government officials and security personnel to defect and join the Taliban as a matter of religious duty. He also noted that the Taliban have created the “Call and Guidance, Luring and Integration” department, “with branches … now operational all over the country,” to encourage defections. [See Threat Matrix report, Mullah Omar addresses green-on-blue attacks.]
Update: On Sept. 19, 2012, The Telegraph reported the Taliban’s claim that their “operations and strategy” have forced the Coalition to “abandon” its plans. “This is an achievement for the mujahideen who have managed to create mistrust among the enemy forces and, God willing, this is the start of their overall defeat in Afghanistan,” said Taliban spokesman Zabihullah Mujahed.
Update: On Oct. 24, 2012, Taliban emir Mullah Omar released an Eid al-Adha message that urged followers to “[i]increase Increase your efforts to expand the area of infiltration in the ranks of the enemy and to bring about better order and array in the work.” The statement continued: “We call on the Afghans who still stand with the stooge regime to turn to full-fledged cooperation with their Mujahid people like courageous persons in order to protect national interests and to complete independence of the country. Jihadic activities inside the circle of the State militias are the most effective stratagem. Its dimension will see further expansion, organization and efficiency if God willing.”
In tabulating the green-on-blue attacks in Afghanistan, The Long War Journal has taken its data wherever possible from ISAF press releases. Additional sources include foreign and US press reports, information obtained from ISAF personnel, and previous LWJ articles. Each listed incident in the timeline includes one or more hyperlinks to sources for the report.
For the purposes of this report, all attacks in Afghanistan in which a person purporting to be affiliated with the Afghan security forces — whether Afghan National Army, Afghan Local Police, Afghan Border Police, Afghan Uniformed Police, Afghan Air Force, other branches, or security personnel hired by Afghan authorities — are considered “green.” Similarly, all persons purporting to be affiliated with US, ISAF, or NATO security forces, including interpreters and civilian contractors, are considered “blue.”
The data below indicates the number of attacks, the affiliation of the attacker (if known), the location/province where the attack occurred, the date of the attack, the number of security forces killed or wounded in the attack, and the affiliation of those killed or wounded. The data also includes the reported fate of the attacker(s).
Because ISAF has generally not reported on green-on-blue incidents in which no casualties have occurred, the overall number of attacks is likely to be far greater than those reported below. Similarly, ISAF has generally not reported on incidents that have resulted only in injuries, not death; these too are likely to be underreported. ISAF has told The Long War Journal that the overall number of green-on-blue attacks is “classified.”
Finally, there may be a slight discrepancy between the LWJ and ISAF overall casualty counts, as ISAF does not treat attacks by Afghan forces on US/NATO civilian contractors as “green-on-blue” attacks. In addition, some incidents initially seen to have involved only injuries may have later resulted in deaths.
The following data will be updated on an ongoing basis to reflect any new attacks.
The Long War Journal‘s data covers green-on-blue attacks in Afghanistan from Jan. 1, 2008 up to the present. As of June 17, 2017, there have been a total of 96 attacks reported.
