In Sicily, the Germans employed a number of the large, six-barreled
Nebelwerfer rocket guns, which could be moved to new positions
very quickly after firing. Although their location could be detected
by the immense flash, it was found, frequently, that a gun's position
had been changed immediately after the flash was observed. For previous reference
to these guns see Tactical and Technical Trends, No. 45, p. 19.
An observer, reporting on these rocket guns, said:
"Attack on the Nebelwerfer, because of the fleeting nature of the
target, demands special attention. The gun can limber up and move out of
position within three minutes after firing. This speed of withdrawal demands
either a very rapid adjustment and immediate fire for effect or else adjustment
on a point 400 or 500 yards away and a surprise transfer going into effect
immediately. The use of speed and surprise is the only way to catch
the Nebelwerfer in position where you can hit it.
"Similar tactics are necessary in dealing with self-propelled roving guns. Because
these weapons can fire for a short time and then change position, they
are difficult to locate. Alert, energetic observers, and quick transfers from
check points within limits to insure surprise, and sudden fire for effect are
the best means of dealing with roving guns."
