The image shows a group of mannequins dressed in military uniforms and helmets, standing in front of a large wooden structure with a sign that reads "Britons You". The structure appears to be made of sandbags and is set up in a room with a concrete floor and a white wall in the background. There are also several other mannequin heads and equipment scattered around the structure, including a ladder, a backpack, and a helmet. On the right side of the image, there is a man wearing a gas mask and carrying a backpack.
