Armor and Shields

The shield is a defensive military equipment used in medieval times. It can be used to block and defend against other weapons such as swords, axes and arrows. However, after the invention on firearms, shields were not as reliable and are not as common.

Did 4th century Roman army wear stainless steel armour?

User Avatar
Stainless steel, as pointed out above, was developed in the early 20th century. Ordinary steel did exist in antiquity. The Romans used steel from Noricum (part of present day Austria), to make swords. Steel is not well suited for armour because it is too hard. However, steel was involved in the making of one of the three types of Roman armour, the lorica segmentata. This was an armour made of overlapping metal plates. The plates had of soft iron inside and mild steel outside using the technique of case hardening. The surface iron was enriched with carbon before putting in the forge. This hardened the surface while leaving the inner metal to remain soft. The harder steel formed only a thin layer, the case of the plate. This hardened the plates without making them become brittle. The lorica hamata a chainmail armour) and the lorica squamata (a scale armour) were made with iron or bronze.

Why was the samurai armor created?

User Avatar
Samurai armour (like all armour) was designed to prevent injuries from various weapons. No warrior was ever perfect and sometimes would let a strike get past their defence, which could easily be lethal. Armour meant a warrior could occasionally make a mistake and not pay so dearly for it. Additionally, the greatest bane of any warrior was the projectile weapon (including long before guns were around), as close combat skill rarely helped against arrows, slingstones, javelins, quarrels or bullets. Armour would provide a real defence against such projectiles as they sought to close in where they could actually fight.

What is a bulletproof jacket made of?

User Avatar
A bullet proof jacket is made from several thin layers of a material known as kevlar ( Kevlar is a registered trade mark). Kevlar is a para-aramid synthetic fibre. Some vests also allow for metal plates to be inserted. While kevlar is light-weight, inserted metal plates make the vest heavier. Though if the vest stops a bullet, I doubt the wearer would mind how heavy the vest was.

What is the history of the roman helmet?

User Avatar
Roman helmets, the galea or cassis, varied significantly over time and between different types of military units. It is thought that originally they were influenced by the helmets of the Etruscans. The Romans then, still in the early days, adopted the bronze helmets of the Greeks. Later the design of Roman helmets were influenced by the design of the helmets of the Gauls. They also had a crest holder. The crest were made with plumes or horse hair. The crest of the legionaries were mounted in a back to front direction, while those of the centurions were mounted transversely. In the later period of the empire they were used only occasionally.

How thick is the metal of an army tank?

User Avatar
That varies with the type of tank, model, and the location. Frontal armor can be very thick (feet), side or rear armor is usually thinner (inches) because it is more likely to be hit in the front than the sides or rear. The armor is also angled to deflect rather than absorb the energy of the shells. "Reactive" armor also contains explosives that detonate when hit to reduce damage from shaped charge armor penetrating weapons. Some examples: The WW2 U.S. Sherman tank used armor varying from about 2 inches to 4 inches thick. The WW2 German Panzer tank used armor varying from about 2 inches to 9 inches thick. However rear top armor was only about 0.6 inch thick. The modern U.S. Abrams tank has armor varying from about 14 inches to 51 inches thick.

What is the difference between a coat of arms and shield?

User Avatar
A shield is a physical item used for a physical defense of a person. A coat of arms is a symbol representative of a person, family, or a country. However, in many languages, the word for shield and coat of arms are the same (such as Spanish - escudo) and most nobles would emblazon their coat of arms on the surface of their shields as a form of personalization of their military gear.
