Technical: badly tramlined print.

Operation Harness took place in waters off the Bahamas "to determine the practicability of conducting Biological Warfare trials at sea"; using greater distances than on Gruinard Island with three bacterial agents. It confirmed the practicability of sea trials and the utility of certain bacteria other than anthrax as agents. (Gradon Carter, 1992)
