Field howitzers are artillery pieces designed for indirect fire, capable of firing shells at high angles. They are typically used in military operations to support ground troops by targeting enemy positions from a distance. Their versatility allows them to fire a variety of ammunition types, including explosive shells and smoke rounds. These weapons are characterized by their relatively short barrels and larger calibers compared to traditional field guns. Field howitzers played a significant role in conflicts such as World War I and World War II, providing essential fire support and contributing to the effectiveness of artillery units on the battlefield.
