In ramping up, you're expending forces, but not actually committing those forces that are ready. In ramping down, you're going to fold those forces back into a ready posture, that is, you are getting ready to go somewhere, being prepared as it were or, indeed, reassigning those forces somewhere else.
In this case, because it is a good example, there's the repatriation of equipment from Afghanistan. It's very, very important that we bring it back, reconstitute it and fix it up, since it has been battered over a number of years, and then put it back with the troops ready to go again somewhere, should that happen. That's a several hundred million dollar effort that ensures that we come out, refit, and get ready to go.
