Hologram

A hologram is a projected three-dimensional representation of a person or object. It is a highly advanced, experimental technology that was never widely used before the Great War.

They were used in the Big Empty and various other government facilities, however the technology was never perfected except in the Sierra Madre. Father Elijah sought the Sierra Madre holograms because of their invincibility - one, deployed in the right place, could wipe out an entire army.
