The term 'Army Units' can refer to a variety of different groups within the military. The most common type of Army Unit is a troop, which is a group of soldiers that are organized and trained to work together in combat or other military operations. TROOPS are typically composed of several smaller units, such as platoons and squads, and are led by a commanding officer. Other types of Army Units include battalions, regiments, and divisions, which are larger groups of TROOPS that are organized into larger formations. All of these Army Units work together to form the backbone of the military, providing the necessary manpower and resources to carry out the mission of the armed forces.
