While some people burn the American flag in the streets, families across America are receiving the most devastating knock imaginable — the moment they are told their soldier husband, father, or son was killed in action protecting the United States of America.

This video shows the human cost of war. The pain; the grief; the loss and the families left behind. The Knock at The Door That Ends a Family Forever.

This video honors the families of fallen soldiers, the sacrifice they endure, and the true meaning of the American flag — a symbol not of politics, but of service, sacrifice, and freedom.
