Holographic projection. The Defense Weekly article describes a quasi-information warfare/psychological operations program that was first discussed by the Air Force after Operation Desert Storm in the Gulf War.
This involves projection of a three-dimensional holographic image to act as a decoy. The Pentagon spoke openly about its use of holographic projections during discussions of its non-lethal weapons program back in 1994. Since then, the program disappeared, most likely becoming a black project.

The article concluded by stating that the U.S. Army's JFK Special Warfare Center and School disclosed back in 1991 that it was looking to develop a 'PSYOPS Hologram System' with the capability to "project persuasive messages and three-dimensional pictures of cloud, smoke, rain droplets, buildings, flying saucers and religious figures.
