Well, we'll have to agree to disagree. When we were rolling, my policy was that all eyes were responsible for scanning for IEDs. The best way to avoid being a victim of one was to was to spot them before they detonated. So, though every one was looking, as dusty as Iraq is, and as old as those HMMWVs were, if you were inside looking out, visibility was poor. Gunner's in a dangerous position, no doubt, but kept everybody safer overall.
