Too impatient by far old chap!
The Coalition have only just started to look, not just too busy before, but not safe to send small units off all over the country on their own until the entire country can be considered secure or sufficient troops are available to provide adequate protection.
They are looking for needles in haystacks, given the size of Iraq, a couple of thousand 45gal drums, split into small packets and scattered throughout the country could take years to find. Artillery shells deliberately wrongly marked could be hidden amongst other ammunition stocks as could smaller rockets.
If it helps a number of what are believed to be trailer mounted chemical weapon laboratories have been unearthed just south of Baghdad.
Just possible that Saddam Hussein will have rigged a few hideous booby traps in the hope that they will be sprung after he has long gone, his way of having the last laugh. Any searches will be painstakingly slow.
