Gun turretA gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Rotating gun turrets protect the weapon and its crew as they rotate.
Siegfried LineThe Siegfried Line, known in German as the Westwall (= western bulwark), was a German defensive line built during the 1930s (started 1936) opposite the French Maginot Line. It stretched more than from Kleve on the border with the Netherlands, along the western border of Nazi Germany, to the town of Weil am Rhein on the border with Switzerland. The line featured more than 18,000 bunkers, tunnels and tank traps. From September 1944 to March 1945, the Siegfried Line was subjected to a large-scale Allied offensive.
NashornNashorn (ˈnaːsˌhɔɐ̯n, German for "rhinoceros"), initially known as Hornisse (German "hornet"), was a German Panzerjäger ("tank hunter") of World War II. It was developed as an interim solution in 1942 by equipping a light turretless chassis based on the Panzer III and Panzer IV tanks with the 8.8 cm Pak 43 anti-tank gun. Though only lightly armoured and displaying a high profile, it could penetrate the front armour of any Allied tank at long range, and its relatively low cost and superior mobility to heavier vehicles ensured it remained in production until the war's end.
JagdpantherThe Jagdpanther (German: "hunting Panther"), Sd.Kfz. 173, was a tank destroyer (Jagdpanzer, a self-propelled anti-tank gun) built by Germany during World War II. The Jagdpanther combined the 8.8 cm Pak 43 anti-tank gun, similar to the main gun of the Tiger II, and the armor and suspension of the Panther chassis. It entered service in 1944 and served on the Eastern and Western Fronts. During the last stages of the war, limited German production resulted in small production numbers, shortage of spare parts, and shortened crew training periods of younger operators.
PanzerjägerPanzerjäger (German "armour-hunters" or "anti-tank troop", abbreviated to Pz.Jg. in German) was a branch of service of the German Wehrmacht during the Second World War. It was an anti-tank arm-of-service that operated self-propelled anti-tank artillery, also named Panzerjäger. Soldiers assigned to tank hunting units wore ordinary field-gray uniforms rather than the black of the Panzer troops, while Panzerjäger vehicle crews wore the Panzer jacket in field gray.
SturmgeschützSturmgeschütz (abbreviated StuG) meaning "assault gun" was a series of armored fighting vehicles used by both the German Wehrmacht and the Waffen-SS formations during the Second World War (1939–1945). The main StuGs were the StuG III and StuG IV based on the Panzer III and Panzer IV medium tank chassis respectively. The more common of the two, the StuG III was developed in the late 1930s on the chassis of the Panzer III.
BunkerA bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes. Trench bunkers are small concrete structures, partly dug into the ground.
BarbetteBarbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name barbette ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase en barbette, which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate.
FortificationA fortification 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 fortis ("strong") and facere ("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.
Anti-tank gunAn anti-tank gun is a form of artillery designed to destroy tanks and other armoured fighting vehicles, normally from a static defensive position. The development of specialized anti-tank munitions and anti-tank guns was prompted by the appearance of tanks during World War I. To destroy hostile tanks, artillerymen often used field guns depressed to fire directly at their targets, but this practice expended too much valuable ammunition and was of increasingly limited effectiveness as tank armor became thicker.
