What is a group of Mortars called?

A group of mortars is commonly called a Volley.

Collective nouns for mortars refer to a group or collection of these military weapons. Mortars are portable, muzzle-loaded artillery firearms commonly used in war and combat scenarios. These firearms are distinguished by their short and wide barrels and are designed to launch explosive shells in a high, low, or medium trajectory to land on enemy targets. While often operated individually, in certain situations, multiple mortars can be deployed together, forming a coordinated force to efficiently bombard a specific area or coordinate fire support. The collective noun "battery" is commonly used to describe a group of mortars. This term draws from historical associations with groups of cannons or artillery pieces, as mortars have historically been considered part of the cannon artillery classification. Like a battery of cannons, a battery of mortars represents a concentrated and coordinated firepower capable of delivering devastating blows to an enemy's position or defensive line. Alternative collective nouns for mortars might include an "artillery section" or an "archipelago," emphasizing the diverse placement of multiple mortars throughout a designated combat theater. By employing various complexes and positioning mortars discreetly, an archipelago reminds us of the dispersed and mobile nature of these powerful firearms. Furthermore, some military units might use terms such as a "platoon," a "company," or a "battalion" to describe their organization of mortars. These terms highlight the hierarchical structure within a larger unit and illustrate the varying scales at which mortars can be organized and deployed, depending on the mission and requirements. In summary, collective nouns for mortars provide a linguistic framework to articulate and describe the organization of multiple mortars within a military setting. These groupings enable more effective deployment, coordination, and concentrated firepower to achieve strategic military objectives.
