Sulphur from the oil fires plus the calcium hypochlorite the military turned foul water into potable water with, creates. Bromism.

I didn't go to the desert, but I gave soldiers going to the desert "vaccinations". The ones going within 24-48hrs got a special thick as karo corn syrup shot in the buttocks, a gammagloblin shot. I went in to save lives, and It haunts me that my fellow servicemen were injured.
I also got certified in potable water abs field sanitation, and this is where the calcium hypochlorite comes in.
If it is DU, the powers that be, would lie to keep their stronger bullets, even though it kills the soldiers, and this is wrong and evil.
