In a gymnasium, a group of approximately ten children, mostly boys, are dressed in matching green outfits with hats, resembling military uniforms. They stand in a line on a wooden floor marked with white lines. A man in camouflage stands to the left of the line, seemingly instructing them. The children are mostly looking forward, appearing attentive and slightly serious. A large speaker is placed behind them, and a net hangs along the wall in the background. The gym has a wooden floor and walls with windows providing natural light.
