Check my comments on DU under the thread on “Different Bullets”.
The M1 tank uses DU as a component of its classified its armor as well as in the sabot “silver bullet” ammunition. It works uncommonly well in both applications. No M1 tanks were destroyed by enemy action during the late war. However, as one person rightly points out, this is at least partially due to a whomping-ass superiority in fire control systems: we shot better every time, usually from twice as far away as they could shoot. This is possible in flat, open country such as the Iraqi and Kuwati deserts. We had the better gun, the better ammunition, the better aiming system, the best circumstances to shoot them under, and we often caught them by surprise.
As I said in the other posting, the main hazard associated with DU is in the heavy metal posioning. As I said there, I’ve worked with it and have nothing wrong with me (as a result of that, anyway). We worried about beryllium posioning from the brakes much more.
I would bet that all the burnt Kuwaiti oil wells didn’t do any good for those who had to breathe all the smoke. After all, crude oil right out of the tap has everything nasty in it. It’s where we get plastics, industrial solvents, and a host of other goodies. The zealous and generous use of a lot of the disease preventatives and various anti-desert bug sprays probably weren’t especially healthful, either.
However, having said all of that I am of the very slightly qualified opinion that Gulf War Syndrome is probably likely at least in part the result of low to moderate level exposure to Iraqi chemical weapons, principally nerve gases. You all may wish to take the time to read about cases where workers were accidentally, negligently, or otherwise exposed to very low levels of nerve gases; the early 80’s book “A Higher Form of Killing” has one or two cases, for instance. The symptoms are strikingly similar to GWS. YOu will also recall that for years the government here denied there was any exposure of our folks over there to chem weapons, then “60 Minutes” showed them where their pants were down by revealing how we hurridely blew up an Iraqi munitions depot known to be stocked to the rafters with nerve and mustard gas weapons. The existence and use of Iraqi chem armed scuds was also denied, but after the ceasefire, we heard all about the inspectors having trouble accounting for such weapons. I suppose fuzing for optimal dispersal of chem agents would be a big problem with Saddam’s chemical scud program, but if you can get the warhead contents dispersed above the target zone by having it intercepted by a Patriot missle, then the problem is solved to some extent. Close enough for a semi-psychotic dictator, anyway. We know it takes very little nerve agent to produce a fatal outcome; it also appears that a very small fraction of that amount can possibly produce long-term nervous system debilitation. I don’t believe there have been many studies in this regard, so evidence appears more circumstantial rather than definitive.
The fact is, we don’t know for sure. What’s worse is that we may not to want to know. It would sure take the bloom off the rose if we were to discover that our nearly bloodless victory was something quite the opposite.
