Breastworks
A breastwork is a temporary fortification, often an earthwork thrown up to breast or shoulder height to provide protection to defenders firing over it from a standing position. A more permanent structure, normally in stone, would be described as a parapet or the battlement of a castle wall. In warships, a breastwork is the armored superstructure in the ship that did not extend all the way out to the sides of the ship. It was generally only used in ironclad turret ships designed between 1865 and 1880.

Fortification
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parapet
A parapet is a barrier that is an upward extension of a wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of the wall, sometimes with a coping at the top and corbel below. *Embattled parapets may be panelled, but are pierced, if not ...

Battlement
A battlement, in defensive architecture, such as that of city walls or castles, comprises a parapet (a defensive low wall between chest-height and head-height), in which gaps or indentations, which are often rectangular, occur at intervals to allow for the launch of arrows or other projectiles from within the defences. These gaps are termed embrasures, also called crenels or crenelles, and a wall or building with them is described as ; alternative older terms are and . The act of adding crenels to a previously unbroken parapet is termed crenellation. The function of battlements in war is to protect the defenders by giving them part of the parapet to hide behind, from which they can quickly expose themselves to launch projectiles, then retreat behind the parapet. A defensive building might be designed and built with battlements, or a manor house might be fortified by adding battlements, where no parapet previously existed, or cutting crenellations into its existing parape ...

Ironclad Warship
An ironclad was a steam-propelled warship protected by steel or iron armor constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, , was launched by the French Navy in November 1859, narrowly preempting the British Royal Navy. However, Britain built the first completely iron-hulled warships. Ironclads were first used in warfare in 1862 during the American Civil War, when they operated against wooden ships, and against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high-seas battleships, long-range cruisers, and coastal defense ships. Rapid development of warship design in the late 19th ...

Turret Ship
Turret ships were a 19th-century type of warship, the earliest to have their guns mounted in a revolving gun turret, instead of a broadside arrangement. Background Before the development of large-calibre, long-range guns in the mid-19th century, the classic ship of the line design used rows of port-mounted guns on each side of the ship, often mounted in casemates. Firepower was provided by a large number of guns which could only be aimed in a limited arc from one side of the ship. Due to instability, fewer larger and heavier guns can be carried on a ship. Also, the casemates often sat near the waterline, which made them vulnerable to flooding and restricted their use to calm seas. Turrets were weapon mounts designed to protect the crew and mechanism of the artillery piece and with the capability of being aimed and fired in many directions as a rotating weapon platform. This platform can be mounted on a fortified building or structure such as an anti-naval land battery, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Established Military Terms
This is a list of established military terms which have been in use for at least 50 years. Since technology and doctrine have changed over time, not all of them are in current use, or they may have been superseded by more modern terms. However, they are still in current use in articles about previous military periods. Some of them like ''camouflet'' have been adapted to describe modern versions of old techniques. Administrative (all arms) * Access control * Base of operation * Cantonment: a temporary or semi-permanent military quarters; in South Asia, the term cantonment also describes permanent military stations. * Chief of defence * Cloak and Dagger * Combat information center * Command (military formation) * Command center * Command and control * Commander-in-chief * Command hierarchy * Defense diplomacy * Defence minister * Directive control * Force multiplication * Headquarters unit * Military facility * Military genius - Clausewitz's attempt to identify cha ...
