Field guns are artillery pieces designed for mobile warfare, typically used by armies on the battlefield. They are capable of firing shells at high angles and are often towed by vehicles or horses. Field guns played a significant role in conflicts from the 19th century through World War I, providing support to infantry units. These weapons vary in caliber and range, allowing them to engage different types of targets. Notable examples include the French 75 mm field gun and the German 77 mm field gun, both of which were influential in shaping modern artillery tactics during their respective eras.
