That was actually a pretty small VBIED. I read the headline expecting something pretty ridiculous, but it wasn't all that big. Car bombs of the middle-east warzone variety pack more than a punch. They usually use bundles of munitions and then some, and it is beyond frightening. If something like that went off, you wouldn't be able to see anything for 10-15 minutes, and the camera would have probably been disabled. So when I read "car bomb", thats what I was expecting. I've seen more than enough of those.
Still, he is really lucky. Even with armor like that, it's not uncommon to have limbs severed from shrapnel.
Also, he's lucky if he walks away without a TBI (Traumatic Brain Injury).
