Danish Army
Specific: Also the GMC CCKW-353
NBC decontamination truck was used by the Danish engineers. The truck
used the M3A3 decontamination apparatus.
Historical: Minor improvements in the design of the
M3A1 Apparatus led to the standardisation of the M3A2 power-driven
Decontaminating Apparatus in 1943. The improvements included an improved
pump, agitator and piping arrangement.
The US Army procured 426 units through WW II and 62 units through the
beginning of the Korea war. One of the major problems with the M3A2 was
that the wooden tanks were made of cypress sapwood that rotted in the
tropics and allowed fungus growth. In 1952 the standardization of the
improved M3A3 with a metal tank resulted the M3A2 being reclassified to
limited standard. The unit was then obsoleted in 1971
