DoD: Gen. Shalikashvili is fond of noting that the nature of war is unchanged, but its character is in constant change. He is exactly right. We are moving toward new warfighting paradigms. These opportunities are available only to those willing to boldly exploit the technological advantages of the type that we currently hold.

SADLER: Stay with us as we move our way [through] Tikrit. So let's just recap as we go through here: Tikrit no coalition forces, Tikrit no fighting, checkpoint ...Shots ring out. OK, that's gunfire. We've just come under attack. Under attack. We're OK, we're OK. Under fire. That confirms our worst fears. If you're with us, we've just gone through a checkpoint, we've come under automatic machine gun fire, and we've blown through the checkpoint. Our armed guard pulled his automatic machine gun and opened fire to get us through there. I think that's as far as we're going to push it today. End of tape, back to Sadler live on CNN.

 

NASA: Microwave radiation is used for radar, transmitting large amounts of information across the country.DoD: These diverse and far-flung activities share at least two common features: First, they are being accomplished in defense of our nation and its citizens; second, they cannot be accomplished without use of the electromagnetic spectrum. That's a hard, cold fact that everyone must face up to. We are not "blowing smoke."
