March 21, 2005: The U.S. Army in Iraq is faced with a dramatic growth in the number of deaths from accidents involving Humvees (â Å“hummersâ ?). Last year, some 39 soldiers died in such accidents. But the rate of accidental deaths from these accidents has doubled in the last four months. That's about five percent of all deaths. Most of the accidents involve new hummers, the ones with armor installed at the factory. The hummer was always considered a safe vehicle, because it had a low center of gravity, and it's width made is less prone to rollovers. But now there are more rollovers, and they appear to be caused by the increased weight of the armor, and the higher speeds troops use to avoid, or get away from, ambushes. Combat casualties have been falling sharply over the past three months, and part of that has to do with the high speed driving tactics adopted by troops using hummers. Such tactics have evolved over the last two years. But all that hot roding comes at the cost of more fatal accidents. The army is studying the situation, and will probably come up with new driving techniques to minimize the dangers.
