From the back of the book:
Ross Rifles is a tabletop role-playing game set in the Canadian trenches of the First World War.
From 1914-1918, Canada played a major role in assisting the British Empire in winning one of the fiercest wars in history. But victory came at a cost. The First World War took the lives of over 60,000 Canadians. It was from this vast entanglement of international alliances, leaders and agendas that Canada emerged as a modern fighting force on the brink of nationhood. In Ross Rifles, you play as soldiers from the Canadian Expeditionary Force struggling to survive the horrors of trench warfare during the First World War. Sent overseas to fight for crown and country, your characters will make personal sacrifices in the name of Canada.
