The Drier Silenced Carbine was a standard weapon in World War II specifically equipped with the British S.O.E.'s Special Operations Unit and a small number of commandos, and the gun was not only an excellent short and medium-range weapon, but also excellently silent when shooting. The Delier silencer carbines were designed by William De Lisle and Sir Campbell.
In early 1942, Delier built three prototypes of the Lee Enfield Mk III* short rifle, two of which were of a 5.56 mm caliber and one of which was of an 11.43 mm caliber, the former semi-automatic and the latter manual.
The 5.56 mm caliber was eliminated due to the military's requirement that special carbines could not be applied to semi-automatic bolts. The 11.43 mm silenced carbine was further refined and refined, and a prototype was manufactured by Ford Degenheim with an improved barrel based on the Thomson submachine gun, with the full name of the Drier carbine engraved on the upper side; the magazine was taken from the modified M1911 pistol magazine (standard 7-round magazine or 11-round magazine extended by 63.5 mm).
The Drier carbine is recognized as the most silent standard firearm of World War II, with an effective range of 250 meters and a silencer diameter of 51 mm, which extends from the base of the barrel to the muzzle position, occupying half the total length of the gun, so there is enough room to absorb gunpowder gas and reduce the initial velocity of the bullet to subsonic. The performance of the silenced barrel is so good that the sound caused when shooting is smaller than the sound of the bolt pulling the bullet to load.
The Drier carbine, which was ready for mass production, had two modes: one was the standard type, with an empty gun weighing 3.74 kg and fitted with a wooden butt in the style of the Lee Enfield rifle; the other was a paratrooper type, with an empty gun weighing 3.2 kg, with a body part that was the same as the standard type, but with a steel folding stock and pistol style grip. After the finalization, the military signed a contract with Stirling for the production of 500 silenced carbines, of which 450 were standard and 50 were paratroopers. From 1942 to 1945, only 129 silenced carbines were introduced, including a Ford Degenheim prototype, a paratrooper prototype and 127 standard models produced by Stirling.

The Delier carbine had a good anti-assassination effect, so it was mainly used by British commandos and special forces for special missions during World War II, and also appeared in British troops in the Malayan Emergency after the war.
The gun appears in the infiltration of the airport section of the game Medal of Honor. It is said that the British army that participated in the first Gulf War carried the Drier carbine, which shows that the performance of the gun is quite reliable, and it also shows the slow development of such small arms in the United Kingdom for many years.

【Weapon Tips】
How does the silencer silence the sound of gunfire? A GIF for you to see
The sound of the gun mainly comes from the bullet out of the chamber, and the huge pressure when the air rushes out of the muzzle will cause shock vibrations to the air outside. The silencer is lined with a lot of sound-absorbing material inside, and the high-pressure gas inside the barrel can expand relatively slowly before spewing out the muzzle. The noise is also significantly reduced due to the reduced speed at which the gas is emitted. Of course, no matter how powerful the silencer is, it cannot be completely silenced, and after the silencer is installed, the sound of shooting is almost as loud as the usual knocking on the door.
