As I said before, from my simple point of view, there are three different groups. There are criminal gangs, people who are just trying to rob people or convoys, etc., and normally the police can deal with that. We also have the drug lords who have large groups of what we'll call soldiers working for them, and they resist any threat to their drug sources. But the largest group are the Taliban.
They don't have any modern equipment. They have equipment that's left over from the Soviet occupation. That country went through a really sad time for 20 to 30 years. If you go there, you see it. The number of houses destroyed is just incredible. One of the consequences is that all over the country there were guns, artillery shells, and rifles. No matter how many we've cleaned up—NATO, the U.S., and the Afghan forces have been able to takes piles and piles of old Soviet equipment out of that country—there's still enough for them to do their job.
When they make these roadside bombs, they are rather rudimentary. They take an artillery shell—usually a 155-millimetre artillery shell—attach a detonator to it and a wire, bury it in the road, and then they put a plank or something in the road with maybe a saw blade, so that when the vehicle goes over it, it makes contact and explodes. So they're not using sophisticated equipment. Most times their roadside bombs are not radio-controlled, although some of them are radio-controlled. That's the level they're at, which is not sophisticated.
