GFM Cloche
The GFM cloche was one of the most common defensive armaments on the Maginot Line. A ''cloche'' (bell) was a fixed and non-retractable firing position made of a thick iron casting which shielded its occupant. By comparison, turrets could be rotated and sometimes lowered so that only the top shell was exposed. GFM is an acronym for ''Guetteur et Fusil-Mitrailleur'' (lookout and rifle-machine-gunner), which describes its purpose as a lookout and firing position for light weapons. Most of the bunkers or blocks in a Maginot Line ''ouvrage'' were fitted with several fixed armoured cupolas or cloches. The cupolas were designed to allow the soldiers to perform reconnaissance or repel an attack with an absolute maximum of cover, from inside the bunker. The armament of each cloche varied significantly, but were typically equipped with some combination of: * Light machine guns or automatic rifles * Vision blocks * Mounted binoculars * A periscope (located on the top of the bell) * A 50&n ...

Fort Schoenenbourg Entree Hommes Detail Tourelle
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek ''Towns of ancient Greece#Military settlements, phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the ancient Roman, Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Th ...

Maginot Line
The Maginot Line (; ), named after the Minister of War (France), French Minister of War André Maginot, is a line of concrete fortifications, obstacles and weapon installations built by French Third Republic, France in the 1930s to deter invasion by Nazi Germany and force them to move around the fortifications. It was impervious to most forms of attack; consequently, the Germans invaded through the Low Countries in 1940, passing it to the north. The line, which was supposed to be fully extended further towards the west to avoid such an occurrence, was finally scaled back in response to demands from Belgium. Indeed, Belgium feared it would be sacrificed in the event of another German invasion. The line has since become a metaphor for expensive efforts that offer a false sense of security. Constructed on the French side of its borders with Kingdom of Italy, Italy, Switzerland, Nazi Germany, Germany, Luxembourg and Belgium, the line did not extend to the English Channel. French st ...

Cupolas
In architecture, a cupola () is a relatively small, usually dome-like structure on top of a building often crowning a larger roof or dome. Cupolas often serve as a roof lantern to admit light and air or as a lookout. The word derives, via Italian, from lower Latin ''cupula'' (classical Latin ''cupella''), (Latin ''cupa''), indicating a vault resembling an upside-down cup. The cylindrical drum underneath a larger cupola is called a tholobate. Background The cupola evolved during the Renaissance from the older oculus. Being weatherproof, the cupola was better suited to the wetter climates of northern Europe. The chhatri, seen in Indian architecture, fits the definition of a cupola when it is used atop a larger structure. Cupolas often serve as a belfry, belvedere, or roof lantern above a main roof. In other cases they may crown a spire, tower, or turret. Barns often have cupolas for ventilation. Cupolas can also appear as small buildings in their own right. The square, ...

Automatic Rifle
An automatic rifle is a type of Self-loading rifle, autoloading rifle that is capable of fully automatic firearm, automatic fire. Automatic rifles are generally selective fire, select-fire weapons capable of firing in Semi-automatic firearm, semi-automatic and automatic firing modes (some automatic rifles are capable of Burst mode (weapons), burst-fire as well). Automatic rifles are distinguished from semi-automatic rifles in their ability to fire more than one shot in succession once the trigger is pulled. Most automatic rifles are further subcategorized as battle rifles or assault rifles. History Maxim In June 1883 Hiram Maxim filed his first patent to do with automatic firearms covering semi-automatic and fully automatic Winchester rifle, Winchester and Martini-Henry rifles as well as an original automatic rifle and blowback- and recoil-operated machine guns, both single and multi-barrelled. Mannlicher In 1885 Ferdinand Mannlicher made an experimental self-loader based on wo ...

Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in Armored car (military), armoured vehicles. More complex periscopes using Prism (optics), prisms or advanced Optical fiber, fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. ...

JM Cloche
The JM cloche was an element of the Maginot Line. It was a non-retractable non-rotating cupola of steel alloy like GFM cloches, but were armed with twin heavy machine guns, as opposed to the lighter automatic rifles associated with the GFM. There were 179 JM cloches on the Maginot Line The Maginot Line (; ), named after the Minister of War (France), French Minister of War André Maginot, is a line of concrete fortifications, obstacles and weapon installations built by French Third Republic, France in the 1930s to deter invas .... JM is an acronym for ''Jumelage de Mitrailleuses'' (twin machine guns). While the MAC 31 heavy machine guns were of the same caliber (7.5mm) as those in GFM cloches, they had a longer practical range and a maximum range of , with a 500 round per minute rate of fire.Mary, Tome 2, page 109 Description The JM cloche closely resembles the GFM cloche in size and construction. It exists in three versions, all designed Model 1930: small, large and two- ...

LG Cloche
The LG cloche was a defensive element common to many Maginot Line ''ouvrages''. The fixed cupola was deeply embedded into the concrete on top of a combat block, with only the top surface visible. The opening permitted the ejection of grenades from the interior of the cloche, providing a means of close defense against enemy troops on top of the bunker. 75 units were installed in the Maginot Line. LG refers to ''Lance-Grenade'' (grenade launcher A grenade launcher is a weapon that fires a specially designed, large caliber projectile, often with an explosive, Smoke screen, smoke, or tear gas, gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary gre ...). Unlike other cloches such as the GFM or the JM, the LG cloche was effectively "blind", possessing a single shuttered orifice in diameter in its flat crown. It had no observation ports at all, as it did not project appreciably above the surrounding surface. The LG cloche came in three mod ...

VDP Cloche
The VDP cloche was an element of the Maginot Line fortifications. A ''cloche'' (bell) was a fixed and non-retractable firing position made of a thick iron casting which shielded its occupant. By comparison, turrets could be rotated and sometimes lowered so that only the top shell was exposed. VDP cloches were used for observation of the surrounding area for artillery direction. VDP is an acronym for ''Vision Directe et Périscopique''. By comparison with the GFM cloche, the VDP cloche had narrower ports and was consequently lower in profile. Description VDP cloches were equipped with three embrasures or crenels for direct vision, providing protection to observers. VDP cloches were also equipped with periscopes that allowed a greater arc of view. The cloches were embedded in a thick concrete carapace over a combat, entrance or observation block element of a largely subterranean Maginot fortification. A platform, identical to that used in the GFM cloche, was installed for the obse ...
