I think it's a question you should ask the department. But if you look at it in terms of complexity and certainty, there's a scale that starts with the RG-31, where we in effect went into the dealership and bought it off the showroom floor, and goes down to the LAV-3, where instead of just popping the turret off and putting on an RWS, we had to do substantially more development work. As you move from off-the-shelf acquisitions to designing, building, and acquiring, the risks go up, particularly the cost and schedule risks.
