For three days in 1971, former US soldiers who were in Vietnam testify in Detroit about their war experiences. Nearly 30 speak, describing atrocities personally committed or witnessed, telling of inaccurate body counts, and recounting the process of destroying a village. The atrocities are casual, seem routine, and are sanctioned or committed by officers. Images from the war illustrate the testimony; there's a side discussion among veterans about racism and a couple of interviews about the soldiers' self-realization. The testimony appears in the US Congressional Record on April 6 and 7, 1971. A "winter soldier" contrasts with Paine's "summer soldier and sunshine patriot."
