Battlefield

A soldier in a gas mask swings a spiked club against a bright, hazy sky, followed by a wide shot of a war-torn battlefield with soldiers, smoke, and a biplane flying overhead. The sequence continues with a soldier firing a weapon in a dark, smoky environment, then a burning aircraft crashing through the sky. The scene shifts to soldiers on horseback charging across a dusty landscape with a biplane in the background, and concludes with a soldier standing on a platform in a jungle, throwing a grenade that releases a cloud of yellow smoke.
