A regiment is a military unit typically consisting of several battalions, which are smaller groups of soldiers. Regiments are often organized by function, such as infantry, artillery, or cavalry, and they serve as a key component of an army's structure. Each regiment has its own traditions, insignia, and history, contributing to the identity of the soldiers within it. In many countries, regiments are part of a larger formation, such as a brigade or division. They are commanded by a colonel or a similar rank and play a crucial role in training, operations, and combat. The term regiment can also refer to a specific group of soldiers within a national army, such as the British Army or the United States Army.
