Members of the Armed Forces come from all over the United States. These citizens choose to serve their country by fighting for it. Some are sailors on the high seas. Some fly airplanes. Others fight on the ground with tanks and guns, but there is much more to service than just fighting. This book looks at the civic responsibility of service where ordinary men and women sign up to defend their country. Using an inquiry based approach, students will learn the facts about military service and understand this important civic service in a format aligned with C3 standards.
