The agency said the force would use undercover officers, decoys and informants to pursue carjackers.

A government intelligence report made public last September acknowledged that emerging missile states were capable of using decoys.

Instead, the Pentagon plans just one more test, using unrealistically simple decoys.

Spring hunters often use decoys, a common combination being a jake and two hens.

It soon becomes apparent that Rex used the other men only as decoys.

In an August 2000 report, he urged flight tests using tumbling decoys and mock warheads.

But they said they might still use decoys in special circumstances.

It takes a long time to learn how to use decoys effectively and many hunters don't do enough waterfowling to gain that level of expertise.

One special difficulty, he conceded, was that the Iraqis "do use decoys, and they use them well."
