An Infantry Brigade is a military unit typically composed of several battalions, primarily focused on ground combat. It usually includes support units such as artillery, engineers, and logistics to enhance its operational capabilities. The brigade is designed to be a self-sufficient force that can conduct various missions, including offensive and defensive operations. Infantry brigades are often part of larger formations, such as a Division, and can vary in size and structure depending on the country and military organization. They play a crucial role in modern warfare, emphasizing mobility, firepower, and the ability to engage in close combat with enemy forces.
