Most of the Iraqi troops seemed to have survived the initial blast, although being that close to such a massive explosion must have left them a bit dazed and confused to put it mildly.

This clip is a couple of weeks old, but a cleaner HD version hit the web yesterday and it’s been going viral ever since. In it, Iraqi forces square off against ISIS and face an inbound truck bomb. Let’s just say things don’t go well for the ISIS crew. The Iraqis manage to get to cover just in time and, given the size of the explosion, they’re lucky they did.

Here’s the official description via WarLeaks, which posted the footage:

Iraqi soldiers faced a huge blast caused by the massive explosion of an IS VBIED right in front their position in Baiji Iraq. The soldiers were aware of the approaching vehicle and took cover behind a mound just moments before the detonation and following shockwave. The attack was filmed from an overwatch position behind the Iraqi line and gives a good overview of the happenings. The attack seems to have apparently failed since the Iraqi soldiers targeted by the SVBIED seem mostly unharmed after the explosion.
