The theme "Freedom is not Free" is depicted in the nineteen battle-clad, stainless-steel troopers, created by Frank Gaylord, warily venturing into the open and heading for a giant American flag. It is particularly moving at night. To their side is a black granite wall, designed by Louis Nelson Associates, into which are etched the faces of more than 2,500 support troops, taken from photos. It's a sea of memories and lives lost in defense of our freedom. Located across the Mall reflecting pool from the Vietnam Veterans Memorial, it was unveiled in 1995.
