In this, the first of his 58 documentary films, John Pilger combines candid interviews and amazing frontline footage of Vietnam to portray a growing rift between the US military bureaucrats - "lifers" - and the soldiers who physically and mentally fight the war on the ground, the "grunts". By 1970, it is an internal sense of disillusionment and frustration born from this rift that is triggering the withdrawal of US forces from Vietnam.
