The Act permitted conscripts (known as "R men" or "zombies") to be used for home defence only and not to be deployed overseas. The "Zombies" were so-called because they were soldiers who could not fight overseas in the war, making them like the zombies of Haitian mythology who were neither dead nor alive, but rather somewhere in-between. In 1942, the Act was amended to remove the prohibition on conscripts serving outside Canada, and the first overseas campaign that NRMA recruits were subsequently involved in was the recapture of the island of Kiska in August 1943. Until November 1944, only those Canadians who had volunteered were sent elsewhere overseas.
