I. INTRODUCTION
Attacks on Coalition forces by Afghan forces -- the so-called green-on-blue attacks -- are emerging as a major threat in the 11-year-old war in Afghanistan. These attacks from within have increased dramatically within the past two years, and so far this year account for 15% of Coalition casualties.
As the United States prepares to complete the withdrawal of its combat troops from Afghanistan by the end of 2014, 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 recent months, attacks by Afghan forces on Coalition forces have surged; they account for 15% of Coalition casualties so far this year. In 2011, green-on-blue attacks accounted for 6%; in 2010, 2%; in 2009, 2%; and in 2008, less than 1%.
Although NATO commanders have 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 in the green-on-blue attacks than NATO admits. 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.
ISAF responses
In May of this year, 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 has become so concerned with the green-on-blue attacks that it has 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 reports.
The surge in green-on-blue attacks has 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 has recently directed all US and NATO troops to carry a loaded weapon at all times, Fox News reported. Other measures being 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 reports 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 involved situations in which soldiers were wounded but not killed.
Update: On Sept. 2, training for more than 1,000 new recruits for the Afghan Local Police was suspended by the US's Special Operations Command after five of its soldiers were killed over the course of a week in August. On Sept. 17, the US military announced that it was suspending most joint US/Afghan patrols in the field until further notice, in the wake of a spasm of insider attacks, a major Taliban assault on Camp Bastion in Helmand province, and widespread Islamist protests over an anti-Islam film. And on Sept. 18, NATO followed suit, announcing that it too was suspending most joint operations below the battalion level.
Taliban claims
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, 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 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. 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, 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.
Methodology
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.
