DETECTIONS OF CHEMICAL WEAPONS In the early days of the air war, chemical weapons detection alarms and tests by U.S., Czech, French and British troops indicated the possible presence of nerve agents and other chemical weapons. This chart pinpoints the dates of detection, nationality of the detection team, chemical agents detected and detection equipment used. The data is drawn from U.S. and Czech military documents.
