Prefab
From CryWiki
A Prefab is a group of brushes and/or entities. For example, you can place a hut and decorate it with props and place weapons inside and then make a prefab out of it. If this prefab is placed in several locations, throughout several levels even, and you choose to change something in the central prefab it will be reflected in all prefabs of this type. Again, like the Archetype entity, good for consistency.
