Right. The challenge with the surge is that it needs to be followed up. I think, by and large, when you surge forces in, they're able to disrupt, which doesn't necessarily have a lasting effect. They're able to clear, which doesn't necessarily have a lasting effect, unless you're able to follow it up with a holding capability. Clearly it will be important to get that effect following from whatever it is the marines do, wherever they do it. And that's well understood by commanders on the ground.
It's a matter of picking the right player off the bench to serve the right purposes and to sequence those in the right way to get an enduring effect, as opposed to a temporary effect.
