A brigade is a military unit typically composed of several battalions, which are smaller groups of soldiers. Brigades are often part of larger formations, such as divisions, and can include various types of troops, such as infantry, artillery, and support units. They are designed to operate independently in combat situations and can be deployed for various missions. In addition to military contexts, the term "brigade" can also refer to organized groups working together for a common purpose, such as a fire brigade or a volunteer brigade. These groups are often formed to respond to emergencies or provide assistance in specific areas, showcasing teamwork and coordination.
