Above is allegedly the picture that led to the attack.

The American soldier served a number of years as a tank crewman, and a year in Afghanistan. He said after the attack 3/4 of the guys in his group decided to go home. Also a number of them were not very qualified. Here is another story linked there. Nine Russian soldiers are trapped in a high rise elevator after they try to use it to go to the top of the building and someone in the building shut it down trapping them, leaving them to be photographed by the security camera. Not very good urban warfare training.
