Originally designed to be used by the second crew member/observer of military airplanes, it was later issued to ground troops. Between May and November 1916 a section was assigned to each infantry battalion of the Italian army and from May 1917 the number of sections was increased to 3 per battalion.
As it was designed to use 9x19mm ammunition, it is said to be the first true

A submachine gun (SMG) is a magazine-fed, automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an autom ...

Due to its extremely high rate of fire, it was nicknamed ''Pernacchia'' (''raspberry'') by its operators.
Design
The Villar Perosa was designed as a portable double-barrel machine gun firing a handgun round. It consisted of two independent coupled weapons, each with its own barrel, firing mechanism, and separate 25-round magazine.
Operational history
![Armamento - Museo de Armas de la NaciĆ³n 114](https://upload.wikimedia.org/wikipedia/commons/2/29/Armamento_-_Museo_de_Armas_de_la_Naci%C3%B3n_114.jpg)
As it was originally designed to be operated from airplanes, it had a high rate of fire of over 1,500 rounds per minute. However, in practice the
9mm Glisenti ammunition was not sufficiently powerful to shoot down aircraft, which had become ever more resistant over the course of the war, and in addition the range was inadequate, so it was eventually dismissed by the
Corpo Aeronautico.
It was also used during World War I by Italian infantry, with a bipod and a
gun shield

World War I era shock troops, due to its high rate of fire and its weight (it was very light for a support weapon), and went under various modifications: Lt. Col. Giuseppe Bassi personally designed a carrying system (consisting of a leather belt fixed to the handles that was later arranged behind the gunner's neck) and a 1.6 kg bipod and removed the gun shield (which weighed roughly 26 kg) to enhance Arditi performances in battle. In his idea, a section of 8 (later 16) VP machine guns had to support the attack of 20 to 30 Arditi armed with rifles, daggers and hand-grenades, giving adequate

and striking the enemy on a psychological level as well. Each weapon was manned by 4 people: a shooter with a backpack or a shoulder ammo bag and 3 ammo carriers, who could take with them up to 5000 rounds.
Some VP machine pistols were equipped with a wooden stock, though the firing mechanism remained unaltered and was not modified in the fashion of, for example, the OVP SMG or the MAB 18.

The mechanism of the VP was a sound design, and shortly after the end of the war was used as the basis of more practical weapons, such as the
OVP submachine gun and the Beretta MAB-18.
