Iraqi Soldiers conducting combat operations against the Islamic State in Fallujah find themselves the target of an Islamic State suicide bomber that they mistake as a friendly vehicle returning to base.

What you're looking at here is a pretty classic case of the Islamic State being able to outwit the Iraqi Army. This isn't a habit that the Iraqis got themselves into fortunately, but early on in the fighting with the Islamic State it wasn't entirely uncommon for the terror group to use military vehicles with their suicide bombers. The vehicles would be able to blend in with the equipment the Iraqi military was using, and, like you're seeing in this video, the suicide bombers would be welcomed behind friendly lines where they could detonate and do a lot of damage.
