This is John Batchel. Blue on Green. That was the category used in Afghanistan to describe attacks by Afghan

nationals. Members of the Army, member of the police force, on American forces, something that grew and grew

into a real threat, as Bill recounts here, toward the end of the 20 tragic years in Afghanistan.

In the most general sense, the tragedy in the District of Columbia these last days was an attack by a veteran blue,

that would be Afghan National Army, on green, two members of the National Guard of the United States.

Blue on green, something that has never actually gone away from concern for the U.S. military.

And here it is again.

Apparently out of nowhere, the allegation is that the shooter was not only a member of the

Afghan National Army, but in special forces, not only in special forces, but in some fashion

attached to the American CIA.

All very mysterious, much to learn but blue on green,

his bill to describe much more of this tonight.

Hello, John, good evening.

Yes, so blue and green attacks, this is something that were quite prevalent in Afghanistan,

particularly during leading up to the U.S. surge in Afghanistan from 2009 to

2013. These are attacks where Afghan security personnel, be it the National Army or police

or other security personnel, would attack American and NATO forces.

And these were significant in Afghanistan.

The Taliban was often driving these.

They were attempting to get security personnel to turn on their American allies,

and they were quite successful.

We documented these at the Long War Journal at the time and these attacks were spiking.
