One of the great powers of virtual reality is we can simulate experiences without taking on real-world risks. The military was one of the first to recognize this benefit in the early 2000s, building tank and aircraft simulators with virtual reality built-in.
The Army is using what it's calling a Synthetic Training Environment to simulate military exercises in a variety of environments. Soldiers will be able to team up with counterparts at 20 locations across the country to train in close-combat environments.
Simulating military exercises will reduce injury, save money, and increase the number of reps a soldier can get in simulated field exercises. Those are all big wins for everyone in the military and virtual reality is making it possible.
