Infantry Immersion Trainer
The Infantry Immersion Trainer (IIT) is a mixed reality training facility prototype for small unit Infantry located in a 32,000-square-foot (3,000 m2) former tomato packing plant in Marine Corps Base Camp Pendleton, California. It has been in operation since November 2007. The original IIT is now known as IIT Phase I. A purpose built IIT was built adjacent to Phase I in Camp Pendleton. A second IIT was built in a historic warehouse in Camp Lejeune, NC and a third was built in MCB Hawaii.
The interior of an abandoned warehouse has been turned into an embattled Middle Eastern town through the use of sets, and special effects such as projections, pyrotechnics, sounds, and smells. The combination of live and virtual training is what makes this an example of immersive training.
The IIT facility is designed to be a decision house for the Marine Rifleman and the Small Unit Leader (SUL); focusing on increasing the tempo of the OODA Loop during which an individual Observes a situation, Orients to it and develops courses of action (COA), makes a Decision, and Acts. Stress inoculation is conducted at the facility where a rifleman is put into multiple situations that in turn replicate the stressors and physiological responses faced in combat, thus building the individuals stress-immune system.
During a visit to the IIT, Chairman, Joint Chiefs of Staff, Admiral Mike Mullen, said, "It's a reminder of what simulation can do. It certainly is great preparation for the marines as they prepare to go to Iraq. Very impressive, very realistic and in the end hopefully, we'll contribute significantly to a better way to execute the mission and save lives."
The IIT facility was built by the Office of Naval Research and PMTRASYS at the request of the Commanding General, I Marine Expeditionary Force (MEF), then LtGen James Mattis, and by elements of the I MEF TEG (Training and Experimentation Group) to include the Battle Simulation Center, to serve as a way to inoculate the Marine Rifleman with the sights, sounds, and smells of the chaotic environment experienced in close quarters urban warfare.
Although it was built quickly, it was based on more than 10 years of training and simulation research.
Three trainers were built, one at Camp Pendleton, second at Camp Lejeune, and another on Hawaii. In 2015, the Hawaii location will take on a Southeast Asia setting, and the ones on the continental United States will be changed to "generic third-world" settings.
