None. The Iraqi shiites are getting tactical support and advice from Iranians, but the troops are Iraqi, including Sunnin tribes and Kurds.
I beg to disgree. This is the Iranian Republican Guard with Russian made weapons leading the onslaught. The #1 Iranian field commander is on the ground. We were caught flat footed but we now don’t have to spend any of our money or lives on this conflrgration. What we have is now a massive war between Shiite and Sunni and that is great!!
