Looks/sounds like he's an Australian defense contractor based there. His dog made some sounds. Both are not shocked by this, just seem to be disappointed/saddened/depressed. Its Afghanistan. I'm sure this is not shocking to them at all, just.. FUBAR. Like all the other unfortunate shit that happens out there that cannot be explained or comprehended, rationally.
Can't blame him for not reacting like us. We're not based there. We don't have to put up with everyday nonsense that they get to deal with. Soldiers and contractors alike. For out of towners, its just another day in the suck.
