It's an elaborate process that has many layers.
First of all, there is a lot of physical security, as we were discussing, to make sure that physical infiltration is not possible.
The other thing that's done is that when a recruit comes in, there is a very elaborate process of identification using the latest technology. We do the background checks to identify the village and the family—and the Afghans actually are pretty good at that kind of thing. If you go into a village, they know the family; they know whence they come. It's not like, say, North America, where brothers and sisters and families are scattered across the country. So when we say there's a check done, it's actually quite an effective means of establishing that a person is who he says he is.
Then their integration into the force is managed, so they are well established within their groups, let's say.
