Thank you for the question.
Yes, there is, although I wouldn't characterize it as a regiment. I would characterize it as a battle group, which is a flexible instrument that is structured to respond to the specific conditions on the ground. It is the army commander's responsibility to maintain forces at that level of capability.
But I would say that we do not hold them at a level of capability that would see us deploy them in two days as a force that big; it would be hugely expensive to hold them at that level of readiness. So we tend to hold them at a level of readiness that is sufficient, within the warning time we think we will have, to be able to bring them up to that very short notice level of readiness so they can deploy on time when we need them.
