Both the Yazidis and Chaldo-Assyrian Christians, from the first day, they formed their armed...and whoever owned a gun. For example, on Sinjar mountain, no internationals went to support them or to save them. They were saved by the local Yazidis, with only very basic weapons, such as AK-47s, and for the Assyrians, it's the same thing.
So, yes, we have more than 5,000 armed Yazidis in Mount Sinjar, and Sheikhan, Bashiqa, and Barzan. They are the ones. Unfortunately, the KRG is against forming any forces. We are screaming for support from the west because we know the KRG is not going to protect us. In fact, they will always try to destroy us.
