A field gun is a type of artillery used by military forces for artillery support in field warfare. They are usually mobile and can be moved easily to different locations on the battlefield. Field guns are designed to be more lightweight and maneuverable than larger artillery pieces, such as howitzers and mortars, and are used to provide direct fire support to infantry and armored units on the front lines. They were widely used in World War I and II, and continue to be in use by many armies today. Field guns are typically classified by their caliber, range, and weight, and can fire a variety of ammunition types, including high explosive, armor-piercing, and smoke rounds.
