Military units are organized groups of soldiers that work together to perform specific tasks and missions. These units can vary in size and function, ranging from small teams, like squads, to larger formations, such as brigades or divisions. Each unit has a designated role, whether it be combat, support, or logistics, and is structured to ensure effective command and control. Units are often categorized by their specialty, such as infantry, armor, or artillery. For example, an infantry unit primarily engages in ground combat, while an artillery unit provides fire support from a distance. The organization of these units allows for coordinated operations and efficient use of resources in military engagements.
