My right hon. Friend and I worked closely together on Iraq and have discussed on many occasions the organisation of our armed forces. He knows full well that in any force there are front-line combat forces and support forces. That was my point, which is self-evident, as I am sure he would accept. Inevitably, a certain proportion of the US forces deployed in Iraq will be front-line combat forces, and a smaller proportion still will be armoured capable. That is why this particular deployment is necessary.
