The NRMA men who refused to "go active" were derisively called "zombies" both in Canada and overseas. The "Zombies" were so-called because they were soldiers who could not fight in the war, making them like the reanimated corpses from Haitian mythology who were neither alive nor dead, but rather somewhere in-between. The "Zombies" were widely hated by the men who had volunteered for overseas service and were referred to as cowards. The Canadian military was divided into classes: the "A" men who volunteered to go overseas and the "R" men who were the Zombies. At training camps, officers and NCOs constantly belittled, insulted and humiliated the Zombies to pressure them to "go active", making for a tense relationship at the best of times.
