large group of uniformed individuals marching in formation on a sunny day. They are wearing green fatigues, helmets (some with visors), and black berets. Each person carries what appears to be a firearm or rifle. The group is moving together in a synchronized manner, suggesting a military or security force. The environment includes a grassy area, possibly a parade ground, with buildings visible in the background. There are also some trees and bushes near the marching formation. The sky is blue with scattered clouds. The overall impression is of a display or training exercise involving armed personnel.
