I'll admit I've never taken a physics course. Perhaps one of the many Roger readers with a Ph.D in physics can explain the principles at work in the following explanation:

Q: Yes, Mr. Secretary. Our soldiers have been fighting in Iraq for coming up on three years. A lot of us are getting ready to move north relatively soon. Our vehicles are not armored. We're digging pieces of rusted scrap metal and compromised ballistic glass that's already been shot up, dropped, busted, picking the best out of this scrap to put on our vehicles to take into combat. We do not have proper armament vehicles to carry with us north.

SEC. RUMSFELD: I talked to the General coming out here about the pace at which the vehicles are being armored. They have been brought from all over the world, wherever they're not needed, to a place here where they are needed. I'm told that they are being -- the Army is -- I think it's something like 400 a month are being done. And it's essentially a matter of physics. It isn't a matter of money. It isn't a matter on the part of the Army of desire. It's a matter of production and capability of doing it.

I think Rummy was expecting one of those pre-screened Republican audiences from the election. Fat chance of finding G.O.P. operatives in a combat zone.
