A garrison is a military post or fort where troops are stationed to provide defense and maintain order in a specific area. It typically includes barracks for soldiers, storage facilities for weapons and supplies, and sometimes administrative buildings. Garrisons can be found in various locations, including cities, borders, and strategic points, to ensure security and readiness. Garrisons play a crucial role in military operations by serving as a base for training, planning, and launching missions. They can also support local communities by providing security and assistance during emergencies. The concept of garrisons dates back to ancient times, with examples found in the Roman Empire and other historical civilizations.
