The LiveLeak poster of the vid below has given the following description to it:
"After ISIS took full control of the Spiker military base, one of the largest in the Salah al Din governorate, more than 1500 Iraqi soldiers were captured and marched off to an unkown destination. Some sources in the area are saying that the number of prisoners is much higher and could be close to 4000 soldiers."
Not surprising that the soldiers surrendered so readily. Most of them must be Sunni and pro-Saudi Arabia ... so the next we hear or see these guys, they will be a part of the ISIS or ISIL terrorist forces.
