It's a difficult one in a theoretical environment, because you could look at just fewer trucks—that's an easy one—or you could look at having the same number of trucks but less capability. My colleague, the vice chief, may offer something here, but that's a trade-off that would be made only with the direction of the experts who understand what the requirements truly are. When you're into army projects versus navy projects versus air force, the army projects tend to be a little more simple in general, and you have more things to play with. If you're looking at a plane or a ship, you see that it's not a decision to go down to fewer ships or planes. The army projects are probably easier examples to get your heads around.
I'll turn to the vice to see if she wants to offer anything here.
