Toward the end of September 1942, it was noted that the Germans in North Africa were
increasing their precautions against British counterbattery fire. Among the methods
used were these:
(1) Harassing missions by day were fired from roving gun positions in the open.
(2) Adjustments were made by using one or two guns sited on a flank.
(3) The fire of both light and medium batteries was directed into the same
area at the same times in order to increase the difficulties of locating
battery positions.
(4) Up to six batteries were fired simultaneously in order to confuse
British sound-ranging. Dummy flashes are also reported to have been used, but
this is not confirmed.
