From the time of the Revolutionary War, when citizens stood forward to defend their liberties against the depredations of tyranny. All the way through Civil War, through the great World Wars, this nation has been defended by the tradition of common ordinary folks who come from behind the plow, come from the store-clerking, come from the classrooms, and so forth to get on the battlefields - ordinary citizens turned into heroes in defense of their liberty, because that's the potential of freedom.
