Mortars are short, portable artillery pieces designed to launch explosive projectiles at high angles. They are typically used in military operations to provide indirect fire support, allowing troops to hit targets that are not in their direct line of sight. Mortars can vary in size and caliber, making them versatile for different combat situations. The projectiles fired from mortars, known as mortar shells, can be equipped with various types of fuses and explosives, enabling them to create significant damage upon impact. Mortars are often used in conjunction with infantry units, providing crucial firepower to support ground operations and enhance battlefield effectiveness.
