Armor in the context of "Vehicle armour"

Aphrodite Areia (Ancient Greek: Ἀφροδίτη Ἀρεία) or "Aphrodite the Warlike" was a cult epithet of the Greek goddess Aphrodite, in which she was depicted in full armor like the war god Ares. This representation was found in Sparta and Taras (modern Taranto). There were other, similarly martial interpretations of the goddess, such as at her Sanctuary at Kythira, where she was worshiped under the epithet Aphrodite Urania, who was also represented as being armed. The epithet "Areia", meaning "warlike", was applied to other gods in addition to Aphrodite, such as Athena, Zeus, and possibly Hermes.

The association with warfare contradicts Aphrodite's more popularly known role as the goddess of desire, fertility, and beauty. In the Iliad, Aphrodite is portrayed as incompetent in battle, being wounded in the wrist by Diomedes under the guidance of Athena, and she is reminded of her role as a love goddess rather than a war goddess like Athena by Zeus. It is possible, however, that this representation was deliberate to assert the Ionian interpretation of Aphrodite, which did not portray the goddess with warlike aspects, as the "correct" version.

Protection is any measure taken to guard something against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring:

Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage serving exclusively as anti-predator adaptations. Many animals supplement the protection afforded by their physiology by burrowing or otherwise adopting habitats or behaviors that insulate them from potential sources of harm. Humans originally began wearing clothing and building shelters in prehistoric times for protection from the elements. Both humans and animals are also often concerned with the protection of others, with adult animals being particularly inclined to seek to protect their young from elements of nature and from predators.

Many clothing materials have been used to make garments throughout history. Grasses, furs and much more complex and exotic materials have been used. Cultures near the Arctic Circle, make their wardrobes out of processed furs and skins. Different cultures have added cloth to leather and skins as a way to replace real leather. A wide range of fibers, including natural, cellulose, and synthetic fibers, can be used to weave or knit cloth. From natural fibers like cotton and silk to synthetic ones like polyester and nylon, most certainly reflects culture.

Humans have shown extreme inventiveness in devising clothing solutions to environmental hazards and the distinction between clothing and other protective equipment is not always clear-cut; examples include space suit, air conditioned clothing, armor, diving suit, swimsuit, bee-keeper's protective clothing, motorcycle leathers, high-visibility clothing, and protective clothing in general.

A shaped charge, commonly also hollow charge if shaped with a cavity, is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry.

A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though depths of 10 CD and above have been achieved. Contrary to a misconception, possibly resulting from the acronym HEAT (high-explosive anti-tank), the shaped charge does not depend in any way on heating or melting for its effectiveness; that is, the jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature; however, the process creates significant heat and often has a significant secondary incendiary effect after penetration.

The armored cruiser was a type of warship of the late 19th and early 20th centuries. It was designed like other types of cruisers to operate as a long-range, independent warship, capable of defeating any ship apart from a pre-dreadnought battleship and fast enough to outrun any battleship it encountered.

For many decades, naval technology had not advanced far enough for designers to produce a cruiser that combined an armored belt with the long-range and high speed required to fulfill its mission. For this reason, beginning in the 1880s and 1890s, many navies preferred to build protected cruisers, which only relied on a lightly armored deck to protect the vital parts of the ship. However, by the late 1880s, the development of modern rapid-fire breech-loading cannons and high-explosive shells made the reintroduction of side armor a necessity. The invention of case-hardened armor in the mid-1890s offered effective protection with less weight than previously.

Plunging fire is a form of indirect fire, where gunfire is fired at a trajectory to make it fall on its target from above. It is normal at the high trajectories used to attain long range, and can be used deliberately to attack a target not susceptible to direct or grazing fire due to not being in direct line of sight.

In naval warfare, plunging shellfire was theoretically capable of penetrating an enemy ship's thinner deck armor rather than firing directly at a warship's heavily armored side.

The Aswārān (singular aswār), also spelled Asbārān and Savaran, was a cavalry force that formed the backbone of the army of the Sasanian Empire. They were provided by the aristocracy, were heavily armored, and ranged from archers to cataphracts.

A panoply is a complete suit of armor. The word represents the Ancient Greek πανοπλία (panoplía), where the word πᾶν (pân) means "all", and ὅπλον (hóplon) means "arms". Thus, panoply refers to the full armor of a hoplite or heavily armed soldier, i.e. the shield, breastplate, helmet, and greaves, together with the sword and spear.

As applied to armor of a later date, panoply did not come into use until the end of the 16th and beginning of the 17th century, and was then used of the complete suits of plate armor covering the whole body.
