That's basically what he said too. The closest I can come to relating to it is August in Georgia near Lake Lanier...that's where I grew up. We'd hit 110 or so usually at least 1-2 days a summer. Only marginally close to Iraq, I'm sure.
At first I thought he would have it easier as a gunner, he'd have the wind as an advantage, but he said it was just like being in front of a blast furnace or something.
