This has been a pretty major news story in the UK leading up to the war, with many UK troops speaking out and saying that if we rush into another desert war now, faulty and outdated equipment will lead to a string of accidents and death. Wonder why it didn't get much coverage in the US? Hmmmm...
Basically, the vehicles and equipment are old and past their best, new guns for the UK army are prone to jamming and clogging (and that's here in the UK, where sandstorms are fairly rare), and the desert sand speeds up vehicle corrosion a hundred-fold. Some of the UK tanks, before the conflict, couldn't even move on sandy surfaces. Good thing they tested it before they shipped out. But how much other stuff wasn't tested?
I doubt this is a cover-up of Iraqi strikes, just more examples of the World's Most Advanced Military Machine not being quite as a well-oiled as we're led to believe. As with the first Gulf War, I fully expect more British troops to be killed by faulty equipment and "friendly" fire than by the enemy.
