How many types of mortar rounds are commonly used?

The correct answer reflects the commonly recognized classifications of mortar rounds in military operations. Mortar rounds are typically categorized into three main types: high-explosive (HE) rounds, smoke rounds, and illumination rounds.

High-explosive rounds are designed to provide lethal effects against personnel and light vehicles through explosive fragmentation. Smoke rounds are utilized primarily for battlefield obscuration, providing cover for troop movements while also signaling or marking targets. Illumination rounds are intended to light up an area during night operations, improving visibility for troops on the ground.

Each of these types serves a distinct purpose on the battlefield, contributing to the versatility of mortar systems. Understanding these categories not only aids in operational planning but also in the effective application of artillery support in various scenarios.
