Virtual
The United States Military has always shown great interest in the potential applications of virtual reality technology.

Today's advancements have now reached a point to where its applications are sophisticated enough to prepare our fighting men and women for the challenges that they face.
INTRODUCTON
There are specific factors that distinguish VR from other simulations.

3D rendered environments
Real-time responsiveness
An immersive sense of participation (Bertol & Foell, 1997, pp. 67-68).
The science fiction motion picture The Matrix (Wachowski & Wachowski, producers, 1999), centers around a virtual world that is completely realistic and immersive.

Today’s virtual worlds are nowhere as sophisticated but developments in technology is heading toward that direction.

It has becoming increasingly difficult to distinguish reality between computer generated images. It is “the holy grail of computer graphics” to achieve such realism (Holtzman, 1997, p. 43).
VIRTUAL WORLDS
1956 - Filmmaker Morton Heilig created the Sensorama which is a projected film based machine that stimulates the senses of a viewer (Carlson, 2008, par. 2).
1961 - Heilig actually patented the idea for what is considered the first Head Mounted Display but the Philco Corportation was the first to actually construct one (Carlson, 2008, pars. 3-4).
1968 - Dr. Ivan Sutherland coupled the immersive device of a HMD with computer technology to "implement the first virtual reality system" (Pausch, Proffitt, & Williams, 2010, par. 2).
1980 - VR pioneer and computer scientist Jaron Lanier and his company, VPL Research Inc. ,was the first to sell and make VR products available (Edge Foundation, Inc., 2010, par. 3).
-He has been attributed to coining the term virtual reality (Beekman & Beekman, 2009, p. 224).
THE EARLY DAYS
HARDWARE AND SOFTWARE
VR systems are not all exactly the same but they do share common in-put and out-put devices.
Head-mounted displays or HMDs
Interactive data gloves that were popular in earlier systems (Vince, 2004)
Common key components shared by VR systems:

A computer-generated world
3D imagery
A particular device for interaction
Software that enables it all to work (Bertol & Foell, 1997, p. 93).
The major software revolves around interacting with a 3D modeled environment.

Computer aided design software or CAD software enables engineers to save time and money (SolidWorks Corp., 2010, par. 1) by first constructing and testing in a virtual world.
VR IN THE MILITARY
The US military first applied VR technology to train pilots in flight simulators. The use of these simulators in the military have been going on since the early 1920's and 30's (Baumann, 2010, par. 2).

VR now helps heal and treat conditions such as post traumatic stress disorder or PTSD. Virtual Iraq is a VR exposure therapy system that makes such treatment possible (Military Health System, 2010, par. 6).

The VIRTSIM is a total immersion training system that incorporates the latest in VR technology (Motion Reality Inc. & Raytheon, 2010).
CONCLUSION
We have examined the following main points

Definition of virtual reality
Virtual Worlds
Early days of VR
Hardware and Software
VR in the Military

Therefore the advancements in technology and VR have now reached a point to where its applications are sophisticated enough to prepare our fighting men and women for the challenges that they face.
