Over the last decade, the collection and sale of data has become a thriving sector. Some services no longer require any real payment in exchange for our personal information. For example, we often agree to connect our social media accounts filled with personal information to certain websites to use their services. This focus on data and information has found its way into the military. Virtual training and simulation are becoming standard practice within the military systems of European states. These produce large amounts of data, which can be analysed and used to optimise training and enhance operational capability. ‘Train as you fight and fight as you train’ is a mantra that can be put into practice more easily with virtual tools, as these tools allow land forces to train in situations that would not be suitable for live training, for example, training in urban areas.
