On the first question, to be as brief and succinct as I can, this is not to make light of your question, but actually the more IEDs we find, the better. If we're finding them rather than detonating them, then we're saving lives. Actually, I'm not sure that you meant the question that way, but a part of the answer is that we actually are finding more by virtue of the equipment capabilities, by virtue of our tactics, by virtue also of support from the local population. The number of IEDs that are reported to us by the locals is on the rise. So in that sense, finding more IEDs is a good thing. Not finding more IEDs, but striking more IEDs, is a bad thing.
There is a dynamic between opposing forces where there's action, reaction, counteraction, adaptation, back and forth, and of course we have done that both with our tactics and with our equipment. The insurgents have done the same thing. There are periods--depending on where they are in their adaptive cycle and where we are in our adaptive cycle--where there will be more or less IEDs. I would actually say that, frankly, over the last two, three, or four weeks, there have been quite a few less IEDs. But in the previous period--if you look at the month of April of this past year and compare it to the month of April last year--there were more.
