The Royal Swedish Academy of War Sciences is a group of people who are really good at thinking about and studying how wars work, like a bunch of smart grown-ups who are very interested in war. They focus on things like how to train soldiers, what kinds of weapons and strategies work best, and how to keep people safe during times of war. They also study how wars have happened in the past so that they can try to figure out how to prevent them from happening in the future. Basically, they are a group of people who talk and write about war all the time to try to make the world a safer and better place.
