Military strategy is how a country or other group like an army plans how to protect itself and defeat its enemies. It's like a big game of chess - the military leaders have to think several steps ahead to figure out the best plan. In this strategy, the military will look at their enemies, their environment (the land or sea where they are fighting), and the tools and weapons they have available to them to make a plan for how to be successful. The plan includes things like where to move forces and when to attack or retreat. Military strategy is extremely important for keeping people safe and winning battles.
