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.
Rocket launcherA rocket launcher is a weapon that launches an unguided, rocket-propelled projectile. History of rockets The earliest rocket launchers documented in imperial China consisted of arrows modified by the attachment of a rocket motor to the shaft a few inches behind the arrowhead. The rocket was propelled by the burning of the black powder in the motor; these should not be confused with early fire arrows, which were conventional arrows carrying small tubes of black powder as an incendiary that ignited only after the arrow hit its target.
Centurion (tank)The Centurion was the primary British Army main battle tank of the post-World War II period. Introduced in 1945, it is widely considered to be one of the most successful post-War tank designs, remaining in production into the 1960s, and seeing combat into the 1980s. The chassis was adapted for several other roles, and these variants have remained in service. It was a very popular tank with good armour, mobility, and a powerful main armament. Development of the Centurion began in 1943 with manufacture beginning in January 1945.
Rocket artilleryRocket artillery is artillery that uses rocket explosives as the projectile. The use of rocket artillery dates back to medieval China where devices such as fire arrows were used (albeit mostly as a psychological weapon). Fire arrows were also used in multiple launch systems and transported via carts. The first true rocket artillery was developed in India by the Kingdom of Mysore. In the late nineteenth century, due to improvements in the power and range of conventional artillery, the use of early military rockets declined; they were finally used on a small scale by both sides during the American Civil War.
TanketteA tankette is a tracked armoured fighting vehicle that resembles a small tank, roughly the size of a car. It is mainly intended for light infantry support and scouting. Colloquially it may also simply mean a small tank. Several countries built tankettes between the 1920s and 1940s, and some saw limited combat in the early phases of World War II. The vulnerability of their light armour, however, eventually led armies to abandon the concept with some exceptions such as the more modern German Wiesel (Weasel) series.
Armoured personnel carrierAn armoured personnel carrier (APC) is a broad type of armoured military vehicle designed to transport personnel and equipment in combat zones. Since World War I, APCs have become a very common piece of military equipment around the world. According to the definition in the Treaty on Conventional Armed Forces in Europe, an APC is "an armoured combat vehicle which is designed and equipped to transport a combat infantry squad and which, as a rule, is armed with an integral or organic weapon of less than 20 millimetres calibre.
Panzer IVThe Panzerkampfwagen IV (Pz.Kpfw. IV), commonly known as the Panzer'' IV, is a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd.Kfz. 161. The Panzer IV was the most numerous German tank and the second-most numerous German fully tracked armoured fighting vehicle of the Second World War; 8,553 Panzer IVs of all versions were built during World War II, only exceeded by the StuG III assault gun with 10,086 vehicles.
M1 AbramsThe M1 Abrams ('eibr@mz) is a third-generation American main battle tank designed by Chrysler Defense (now General Dynamics Land Systems) and named for General Creighton Abrams. Conceived for modern armored ground warfare and now one of the heaviest tanks in service at nearly , it introduced several modern technologies to US armored forces, including a multifuel turbine engine, sophisticated Chobham composite armor, a computer fire control system, separate ammunition storage in a blowout compartment, and NBC protection for crew safety.
Mortar (weapon)A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Mortars have been used for hundreds of years.
BlitzkriegBlitzkrieg (ˈblɪtskri:g , ˈblɪtskʁiːk; from Blitz 'lightning' + Krieg 'war') is a word used to describe a combined arms surprise attack using a rapid, overwhelming force concentration that may consist of armored and motorized or mechanized infantry formations, together with artillery, air assault and close air support, with intent to break through the opponent's lines of defense, dislocate the defenders, unbalance the enemies by making it difficult to respond to the continuously-changing front, and defeat t
