Here is a forensic description of the video: A group of uniformed men are standing in formation, clapping and singing. They are dressed in dark uniforms with matching caps. The caps have a badge on the front. The men appear to be outdoors, in a grassy area with trees visible in the background. The sky is overcast, and the lighting is somewhat flat. The men are facing towards the camera and clapping in sync. The man in the front row on the right side of the frame is singing.
