'Sir! No Sir!', is a film on the GI anti-war movement during the Vietnam war.
From the film website ... The Vietnam War has been the subject of hundreds of films, both fiction and non-fiction, but this story–the story of the rebellion of thousands of American soldiers against the war–has never been told in film.This is certainly not for lack of evidence. By the Pentagon’s own figures, 503,926 “incidents of desertion” occurred between 1966 and 1971; officers were being “fragged”(killed with fragmentation grenades by their own troops) at an alarming rate; and by 1971 entire units were refusing to go into battle in unprecedented numbers. In the course of a few short years, over 100 underground newspapers were published by soldiers around the world; local and national antiwar GI organizations were joined by thousands; thousands more demonstrated against the war at every major base in the world in 1970 and 1971, including in Vietnam itself; stockades and federal prisons were filling up with soldiers jailed for their opposition to the war and the military.
