The military police was also called into action during the austerity period in Israel, to combat the increasing black market on October 5, 1950. Roadblocks were set up and military vehicles were pulled over. Construction materials, furniture, home supplies, clothes and food were found in large quantities. The Criminal Investigations Division led the investigation efforts, which helped put many contrabandists in jail. In 1952, the Aluf Moshe Dayan of the Southern Command ordered the military police to instill order in the immigrant camps and "ma'abarot" in the south of the country.
