Afghanistan: Green-on-Blue Attacks in Context


Published: 01 November 2012

October 31, 2012 — Written By: R. Hossain


The spike in green-on-blue attacks (also known as "insider attacks") in Afghanistan in 2012 is a worrying development that has the potential to endanger the International Security Assistance Force's (ISAF) mission to train and prepare Afghan security forces for the challenges of stabilizing the country. It is important to establish both the scope of the green-on-blue threat as well as the context in which the attacks occur.

General trends in green-on-blue attacks

From 2007 to 2012, there have been 69 documented green-on-blue attacks. It is difficult to draw definitive conclusions about the principal causes of these attacks given the small total number of incidents, but there are discernible trends.

First, insider attacks have increased in frequency over the past few years. Based on available information, there were two green-on-blue attacks in 2008, five in 2009 and 2010 each, 15 in 2011, and 40 in 2012 (as of October 31). Insider attacks were largely concentrated in the Southern, Southwestern, and Eastern regional commands. More than half of all attacks in 2012 occurred in Kandahar and Helmand, which were the focus of the counterinsurgency campaign during the "Surge."

Insider attacks are a complex phenomenon, and the trends in the data do not demonstrate causality. Instead, visualizing this data highlights the specific context in which each attack occurred. One notable anomaly is a complex attack on September 29, 2012, in which a group of apparent Afghan National Army soldiers ambushed a U.S. patrol from multiple directions at a checkpoint in Wardak, possibly with the aid of insurgents.

Possible explanations for the 2012 increase in green-on-blue attacks

There are two main narratives purporting to explain why green-on-blue attacks happen and why they are happening more frequently: grievances and infiltration. Grievance-based insider attacks occur because of cultural misunderstandings between foreign and Afghan troops, low morale, and revenge for perceived insults or provocations. Attacks caused by insurgent initiative are pre-planned violence organized by groups like the Quetta Shura Taliban or their Haqqani Network associates who have infiltrated the ANSF or influenced existing members to execute attacks.

The Pentagon believes that the vast majority of green-on-blue attacks are grievance-based rather than a result of infiltration, and on August 23, 2012 Gen. John Allen estimated that 25% of the attacks come from Taliban infiltration. In contrast, on October 4th, Afghan Deputy Foreign Minister Jawed Ludin described the majority of insider attacks as the result of "terrorist infiltration" rather than cultural differences. Another theory cites the rise in attacks in 2012 as a result of copycat behavior. Meanwhile, the Taliban claims credit for nearly every attack.

It is also important to consider the opportunity that green-on-blue incidents provide to insurgents in Afghanistan. Several indicators suggest that the Taliban is seizing on green-on-blue attacks as an opportunity to achieve a psychological effect in the U.S., responding to U.S. media coverage of prior incidents. Indicators include recent observations of a greater degree of coordination prior to attacks as well as a minor trend in copycat behavior emanating from attacks in Helmand. The sharp rise in attacks during Ramadan in 2012, which breaks from trends observed in former years, may also be interpreted as deliberate.

    Get a clue. You're dealing with Islam here. Why are they working so hard to justify what they do. There is no justification.
    This is not a war...this is a political scam on the American people. Bring our men home...we don't need to sacrifice anymore of them playing political games. If Afghanistan or any other muslim country threatens us again....wipe them out from the air. Do it once and the rest might listen then and leave us the....heck alone for awhile.

    Looking over this trove of information on the subject, I have to ask, how is the average American, even if, they are interested, supposed to wrap their collective heads around something like this :-?

    The very immensity and diversity of this mostly arid throw back to the middle ages, is enough to send most of the average public's head spinning like a dervish

    What can the "concerned" even do about something so horrendous as having to live under the constant stress of being attacked in your own RAOC, much less out in the field where at least you have situational awareness and have somewhat of a fighting chance :sad:

    Ask the folks from Vietnam how they felt living among the "enemy"? Go back through the hysterical records of the Russians, the British and everyone else who came to "CHANGE" Af-Pak, or the whole middle east for that matter :eek:

    This is not a new phenomenon, nor should it be a surprise to anyone with a working knowledge of the cultural history of the Af-Pak theater

    Obviously the current leadership, military and civilian, is either unaware of this information or they just don't care for whatever reason :-?

    One thing is for certain judging history as a guide, if we have any HOPE for success in Af-Pak, we now have only two options, CHANGE the current policies to fit the mold in which they have to operate successfully, or get the hell out, fast :eek:

    Know your enemy. Shariah law forbids Muslims from siding with non-Muslims against Muslims, especially in taking up arms. For a Muslim to assist a non-Muslim to kill another Muslim means apostasy and the death penalty. How do U.S. troops not know that by now? Get past the empty rhetoric and actually read the sources

    The reason for the increase in green-on-blue killing is the same as we saw when Israel announced it was pulling out of south Lebanon. The attacks and IEDs INCREASED. Why, because they will claim they chased us (or US) out. Worse than the blatant lies, they actually, if not eventually, seem to believe it.
