A military unit is a group of soldiers organized to perform specific tasks and missions. These units can vary in size, from small teams like a squad to larger formations such as a battalion or brigade. Each unit has a designated role, whether it's combat, support, or logistics, and is essential for the overall effectiveness of the military. Units are often made up of different specialties, including infantry, artillery, and engineers. For example, an infantry unit focuses on ground combat, while a logistics unit ensures that troops have the supplies they need. Together, these units work to achieve strategic objectives in military operations.
