ELI5: Explain Like I'm 5

Military simulation

Military simulation is like playing a game, but it’s used to help the military practice and prepare for real-life missions. It’s like playing a very realistic video game, except it’s used by the military to learn how to be better at actual warfare. Through military simulation, they can practice using weapons, practice strategy and develop new skills. They also use the simulations to see how they would fare in certain situations and how they could better prepare for them.
