A battalion is a military unit typically consisting of 300 to 1,000 soldiers. It is usually made up of several companies, which are smaller groups of soldiers. Battalions are often part of larger formations, such as brigades or regiments, and are commanded by a lieutenant colonel. They play a crucial role in ground operations, providing a balance of firepower and personnel. Battalions can be specialized based on their function, such as infantry, artillery, or armored units. Each type of battalion has specific training and equipment tailored to its mission. For example, an infantry battalion focuses on foot soldiers, while an artillery battalion operates heavy weapons like cannons and rockets.
