You may have heard of the "ghost army" of World War II—a set of rubber tanks used by the US Army to mimic active battlefields in Europe. What you may not know was the tanks were accompanied by an equally fake soundtrack of battle noises. Even more surprising? This "sonic deception" was developed by a team of the ASA's founding members whose contributions were almost lost to history. In this episode, we talk with Walter Montano (ARQUICUST Argentina Peru) about the innovations that helped save thousands of lives during the war.
