You have to do a multi-faceted set of things, and none of them will be perfect. I think there will be a number of things we can do in the intelligence domain to watch for these efforts and to try to guard against them and to warn when they're happening. But a number of things will have to be done by the force generators in army, navy, and air force once those threats have been raised and highlighted, as they have been, to prepare their ships and aircraft and the individual human beings who are actually going to be in those areas to recognize those things when they're starting to happen and to deal with them appropriately. What is happening on the training front, to be honest, in terms of what specific actions we're taking probably involves a level of detail that I can't get into.
