Medium tanks are versatile armored vehicles designed for a balance of firepower, mobility, and protection. They typically feature a turret-mounted cannon and can engage both infantry and armored targets. Medium tanks are often used in combined arms operations, supporting infantry and other units on the battlefield. These tanks emerged during the early 20th century, with notable examples including the M4 Sherman from World War II and the T-34 from the Soviet Union. Their design allows for effective maneuvering in various terrains, making them suitable for offensive and defensive operations in modern warfare.
