Propaganda has been a staple of warfare since ancient fighters began screaming "Surrender or die!" Today, psychological weapons are being tested at Dugway Proving Ground and shipped to the Persian Gulf.

John Slater, leaflet project officer, confirmed Friday that the Army is testing propaganda leaflet cannon shells that eject about 1,000 leaflets per shell. The destination and number of shells can't be disclosed, but the manufacturer is shipping them to the Saudi Arabia area."So far in our testing they have been successful," he said Friday. Instead of leaflets, during tests the shells eject slips of paper showing only the test number.

If war breaks out, Army Special Forces would use howitzers to fire the shells into enemy territory. Timed fuses would eject messages, which would flutter to the ground while the shell casings whiz on to hit some selected unpopulated area.
