Name one key component of a mortar system.

A mortar system is essential for indirect fire support on the battlefield, and one of its key components is the mortar tube. The mortar tube serves as the main component from which projectiles are launched. It is designed to withstand the high pressures generated during firing and is typically mounted on a baseplate for stability. The tube's angle can be adjusted to achieve the desired range and trajectory for the mortar rounds, allowing for accurate targeting of enemy positions. Understanding the role of the mortar tube is crucial for effective operation of the mortar system in various combat scenarios.
