In a well-lit indoor gym with wooden floors marked by lines, a group of about eight children are performing a choreographed song and dance. Dressed in matching, olive-green military-style costumes with hats and belts, and wearing what appears to be a red decoration on their chests, they stand in a line and execute synchronized leg movements and hand gestures. In the background, there is a ladder-like climbing frame attached to the wall, and a net is stretched across the gym. Large windows provide natural light.
