Virtual reality could almost be made for military applications, since the key advantage of simulating as opposed to actually engaging in a conflict situation is that nobody gets hurt. According to Brigadier SC Sharma, president of Axis Aerospace, "The military uses VR for everything from training and safety enhancement to analysing military manoeuvres and battlefield positions". Given even a basic understanding of what teenage gamers do with PS4s, it's easy to imagine how a more immersive version could provide training for real soldiers. In fact, VR can be extended to the battlefield itself and used as "battlefield visualisation", says Sharma, "to control combat operations in real time and help commanders assess their options".
