Quinn's character is taken prisoner by the U.S. 24th Infantry Division in 1945. This couldn't have happened as the 24th was fighting in the Philippines at that time and would later be sent to Japan on occupation duties.
It is mentioned that Romania was overrun in the war by the Soviet Union on April 20th 1944, whereas in fact, Romania capitulated on August 23rd 1944, following August 22nd's lost battle of Iasi.
