The military wants its soldiers to be as skilled as possible, and in order to achieve this they require proper training. One of the things that is used to train soldiers are computer simulations. These simulations are used to put a soldier in dangerous circumstances and observe his reactions. It is interesting to note that simulations like this have changed dramatically during the last decade, and are a lot of more realistic right now. I believe that this is due to the fact that computer games became so popular and eventually consumers demanded better and better games. The graphic engines used in games played for entertainment can be used in simulations made by the army. This is how games influenced the way military can perform their training of soldiers.
