A field gun is a type of artillery designed for use in open terrain, typically on the battlefield. It is characterized by its relatively lightweight and mobility, allowing it to be easily transported and repositioned. Field guns are usually equipped with a rifled barrel, which improves accuracy and range, making them effective for both direct and indirect fire. Historically, field guns played a significant role in various conflicts, including World War I and World War II. They were often used to support infantry units and could fire explosive shells, shrapnel, or other types of ammunition. The development of more advanced artillery, such as howitzers, eventually led to a decline in the use of traditional field guns.
