The Battle of Brains was wartime propaganda printed in 1943 designed to encourage young Canadian men and women to sign up for the military. Interesting, when the government wants its young men and women to risk their lives, they are "citizens", but once they actually give up their lives for their country, citizens they are NOT.
"Every citizen has, in wartime, a very special duty to his country, his community, and to himself as a citizen of that country. You have taken the first step in the discharge of the duties that have befallen you. You are now receiving traning through which you become mentally and physically better equipped to perform those duties. You may rest assured that the other citizens of Canada who are at their civilian posts, watch you with pride and in many cases with envy."
