Mortars

Authored By Staff Writer | Last Updated: 4/1/2014

The basic principles behind the mortar weapon system allow for relatively portable, indirect firepower to be brought into any offensive action.

Even before their large-scale use in World War 1 and World War 2, the mortar held a history dating as far back as the 18th Century. Mortars were designed as "indirect fire" weapons intended to lob projectiles against enemy positions that were protected by walls or natural coverage. The "lobbing" nature of the mortar ensured that the projectile would clear the obstruction and engage the enemy behind it. The use of mortars in combat was not as prevalent prior to World War 1 but the trench warfare nature of that conflict brought about its heavy use. As such, various-caliber mortars were in large-scale use by the end of the war. In World War 2, many pre-war designs were still en vogue while newer ones came into play. From then on, the mortar has remained a vital cog in the modern military machine.
