The Last Witness

After credits: "In 1990, Soviet President Gorbachev admitted that the Soviet Union was responsible for the murders of Polish prisoners of war at Katyn in 1940. No one was ever prosecuted. In 2012, declassified documents proved that the U.S. government suppressed information that attested to Soviet guilt. No British government has ever publicly charged the Soviet Union with responsibility for the Katyn Massacre. This film is dedicated to the 22,000 Polish prisoners of war murdered in the Katyn Massacre and to those murdered in the years that followed so that the truth would remain buried forever."

Between 00:07:37 and 00:07:49 a male and female soldier can be seen exchanging documents and talking.

The male soldier quite clearly has three white stripes on his right arm indicating he is a Sergeant (Sgt).

The female soldier quite clearly has one strip on her left arm indicating she is a Lance Corporal (L/Cpl)

Both Sgt's and L/Cpl's are Non Commissioned Officer (NCO) ranks in the British Army.

Before parting ways the Male soldier salutes the female soldier and the female soldier returns the salute.

This is not accurate. Only commissioned Officers are saluted in the British Army.
