The slow-motion effects used during tank battles to illustrate the impact of rounds hitting tanks might be very unsettling for sensitive viewers - especially those who are not used to the intensity of war movies. However, it should be noted that the idea behind these slow-motion effects are much more relevant to technical and special effects aspects and are clearly not used to distress viewers.
There is one scene where POW's arrive at a concentration camp - the scene contains some very intense psychological aspects; for example a Nazi-officer cocks a pistol and points it at a prisoner's face. He pulls the trigger, but the pistol misfires.
There is another scene where a Nazi-officer cocks his pistol and threatens to shoot a Russian girl. He counts from one to five while pointing the pistol at her - she starts crying and collapses against a wall.
