I've said in the defence department that our hard-core function in the Kandahar area is reconstruction. The PRT is the key for us, from a military point of view. The battle group is there to try to create a security environment so that PRT can be at its highest level of efficiency. We're moving in 125 more infantry to protect the PRT, so they can get on with their activities. Beyond projects, they also meet all the elders and try to keep in contact with the various tribes. So we're putting an extra infantry company in to protect them. The battle group, which will be reinforced by a tank squadron, will be there to try to create enough security for the PRT to operate. But the PRT is the key. It's the key to it all. We have to make the lives of the Afghans better.
