A mortar is a tool for war. 
A mortar is a metal tube. 

A mortar is a tool used to shoot bombs. 

Mortars have been used for hundreds of years. Long ago, they were very heavy. They looked like big iron bowls. 

To use a modern mortar, a soldier drops a bomb into the tube. The bomb hits a firing pin at the bottom. This makes the bomb launch. Most mortars use a base plate. This plate sits on the ground to soak up the kick. Some mortars are even put on trucks or tanks. These are called mortar carriers.
A mortar is a special kind of cannon used to launch explosive shells. These shells are often called bombs. 


How does a mortar work? The way it works depends on the design. In a modern Stokes mortar, a soldier drops a bomb into the tube. 

Mortars have a very long history. The earliest use was in Korea during a naval battle in 1413. 

There are many different types of mortars used in history. During the American Civil War from 1861 to 1865, General Ulysses S. Grant used mortars made from tough wood. 


Today, you might see mortars used in many ways. Some are small enough for a soldier to carry on their back. Other mortars are part of a big vehicle. 
A mortar is a specialized type of artillery weapon designed to launch explosive shells. These projectiles are often technically referred to as bombs. 
Modern mortars are typically lightweight and man-portable. A standard setup consists of a metal tube, which is usually smooth-bore but can sometimes be rifled. This tube is fixed to a base plate designed to spread out the recoil, or the backward kick, from the launch. The weapon also uses a lightweight bipod mount and a sight for aiming. To understand the mechanism of a modern Stokes mortar, imagine dropping a weight into a tube. When a soldier drops a mortar bomb into the tube, an impact-sensitive primer at the base of the bomb hits a firing pin. 
Mortars have a long and varied history spanning hundreds of years. The earliest recorded use occurred during a Korean naval battle in 1413. 

As technology progressed, mortars became more mobile and specialized. In 1701, Baron Menno van Coehoorn invented a transportable mortar. This version fired exploding shells with fuses lit by hot gases. This innovation led to the creation of new naval ships called bomb vessels. During the American Civil War from 1861 to 1865, mortars were used in many ways. General Ulysses S. Grant even reported making improvised mortars by boring out logs of tough wood and binding them with iron bands.
Different types of mortars serve very different tactical roles. During World War I, the German Army used short-range trench mortars called Minenwerfers. 


Modern warfare also utilizes mortar carriers and gun-mortars. Mortar carriers are vehicles that carry the weapon as a primary tool. 
Today, the evolution of the mortar continues through advanced systems. The Israeli Merkava tank even uses a mortar as a secondary armament.
