Vocal opposition to President’s Bush’s strategy of sending more than 20,000 additional troops to help secure Iraq has grown to include some of the troops themselves.

A group of more than 50 active-duty military officers will deliver a petition to Congress on Tuesday signed by about 1,000 troops calling for an end to the U.S. occupation of Iraq. “Any troop increase over here will just produce more sitting ducks, more targets,” said Sergeant Ronn Cantu, who is serving in Iraq.

Under the 1988 Military Whistleblower Protection Act, active duty military, National Guard, and Reservists may communicate with any member of Congress without fear of reprisal, even if copies of the communication are sent to others.
