As this question is in the "Canada In World War Two" folder, I would imagine the person wants to know about the specifics of the conscrition crisis in Canada, during that war. During WW2, Canada had two types of soldiers, those that "volunteered to fight" and those that "refused to fight" The first group went overseas and fought and represented Canada very well, while the second group sat on their asses in Canada, being paid and fully trained, but refusing to fight. They were called "Zombies" and most were from Quebec. Cowards every one. Even today, Canadian WW2 veterans have very little good to say about the Province of Quebec and the cowards that were the ZOMBIES. Jim Bunting. Toronto.
Many conscripts went to other bases, Germany, etc. If you are investigating the "draft dodgers" then I think that a general amnesty was granted in the late 1970's. I came to Sweden in 1970 but was not conscripted as some of the Americans who came here then were (There was a lottery and my birth date was way down the list).
Medics in WW2 did the same thing medics did in all of the other wars--they helped the soldiers in the units they were assigned to. Their job was to go into battle with the soldiers and to treat wounds as they happened and to help the wounded soldiers get back from the battlefront. When the soldiers were not in battle, they acted as medical personnel to treat any minor wounds or problems the soldiers might have had.
Well there were many soldiers used in the WW1 but the main ones are volunteers, these are people who volunteer to go for the war, there are conscripts who are soldiers that were meant to be going into the war and lastly there were boy soldiers how were soldiers that younger that the actual age to be a soldier.
