The picture has something of this: people, man, group, military, weapon, war, soldier, wear, gun, lid, army, two, rifle, woman, veil, skirmish, battle, group together, child.
Perhaps it’s a painting of a group of men standing next to each other in a field with a flag on top of one of the men’s shoulders.
