A military unit is a group of soldiers organized to perform specific tasks within a military structure. Units can vary in size, ranging from small teams, like squads, to larger formations, such as battalions or brigades. Each unit has a defined role, such as combat, support, or logistics, and is led by officers who ensure that missions are carried out effectively. Military units are essential for coordinating operations and maintaining discipline within the armed forces. They often train together to build teamwork and efficiency. Examples of military units include the Army, Navy, Air Force, and Marines, each with its own specialized units.
