group of people gathered on a dirt field, performing what appears to be a choreographed dance or drill. There are at least two red flags planted in the background, slightly off-center from the group. Palm trees surround the field, indicating a tropical or subtropical environment. The sky is clear and blue. Some of the people are wearing white shirts, but their lower garments are dark in color. The perspective is from a slightly elevated position, looking down onto the field. A person can be seen off to the side, facing the group, possibly directing them.
