The last group, the collection team and a special radar technical expert, moved forward to take the target. The collection team slipped through enemy defender positions, entered the installation, and found the radar. They used hacksaws, crowbars, and precision hand tools to dismantle the main components. As each part of the radar was exposed, it was sketched and photographed. The team also captured a German signalman—the radar operator.
When they finished, the team destroyed what they couldn't take with them and began their move to the beach under progressively heavy fire. The surviving commandos were picked up by Allied landing craft and escaped across the Channel to England. Exactly three and one-half hours after the mission began it was over. Although two men were killed, six wounded, and six more listed as missing in action, the raid was deemed a great success. Not only was it the first raid on the continent following the disaster at Dunkirk but also it resulted in the successful capture of a valuable piece of enemy material—material that later proved to be of vital TECHINT interest.
Allied TECHINT experts examined the material as soon as they got it. The exploitation of this radar, along with the sketches and the photographs, quickly began to provide valuable TECHINT. For example, just from the recovered metal manufacturer's plates, analysts accurately determined how many Wuerzburg radars had been produced and their current rate of production. When the German signalman was interrogated, he provided valuable information about the level of operator skills and operator training. Most important, though, TECHINT scientists used the captured material to build an operational Wuerzburg radar mockup.
When the mockup was completed, they had a multifrequency radar that seemed, at first, to be almost impossible to jam. Scientists went to work to develop countermeasures to neutralize the radar's capabilities. Their efforts resulted in thin metallic strips cut to different lengths that could be dropped from airplanes. These strips reflected radar signals and effectively jammed the new radars. They dubbed these strips chaff . CHAFF turned out to be one of the most successful countermeasures developed during World War II—being particularly useful during the Normandy Invasion. THE KOREAN WAR :
It wasn't until the beginning of the Korean War, when North Korean troops in Soviet-designed and Chinese-built armor rolled south, that the United States discovered it had little confirmed data on enemy weapons systems. 1-4
