What type of weapon is a howitzer?

A howitzer is categorized as a support artillery weapon because it is designed to fire shells at high angles and is primarily used to provide indirect fire support for ground troops. This type of artillery is effective for delivering explosive firepower over long distances, which is essential in a variety of battlefield scenarios. Howitzers can engage targets that are out of the line of sight, allowing them to hit enemy positions from concealed locations. This capability underscores their role in supporting infantry and armored units by softening up enemy defenses and providing suppressive fire to facilitate troop movements. In contrast, the other options describe weapons with different roles or functions that do not align with the characteristics and intended use of a howitzer.
