The Chameleon Factor (Stony Man Series #74)

Stony Man
Their orders come direct from the Oval Office--and only when the situation is desperate enough to call for swift hands-on measures. Stony Man's cybernetics team and tactical commandos are put into action to remove threats against America with surgical precision. Now it's crisis time, and the situation is big--a Level-10 security clearance, For the President Only. And for Stony Man, it's one shot, no second chances. . .

Chameleon
A brilliant new development in portable stealth technology, Chameleon is a state-of-the-art jamming device that blocks all kinds of magnetic frequencies, making it the ultimate death shield in the right hands. But in the wrong hands, it would mean the obliteration of America's defense and communications systems--and open season on its citizens. When Chameleon is stolen by a traitor who provides a fiery demonstration of its doomsday power, Stony Man must retrieve it at any cost.

If Chameleon is deployed. . .shutting it down is not an option.
