Turtle Ship
A ''Geobukseon'' ( ko, script=Hang, 거북선, ), also known as turtle ship in western descriptions, was a type of large Korean warship that was used intermittently by the Royal Korean Navy during the Joseon dynasty from the early 15th century up until the 19th century. It was used alongside the panokseon warships in the fight against invading Japanese naval ships. The ship's name derives from its protective shell-like covering. One of a number of pre-industrial armoured ships developed in Europe and in East Asia, this design has been described by some as the first armored ship in the world. The first references to older, first-generation turtle ships, known as gwiseon (귀선; 龜船, ), come from 1413 and 1415 records in the ''Annals of the Joseon Dynasty'', which mention a mock battle between a ''gwiseon'' and a Japanese warship. However, these early turtle ships soon fell out of use as Korea's naval preparedness decreased during a long period of relative peace. Turtle sh ...

Replica
A 1:1 replica is an exact copy of an object, made out of the same raw materials, whether a molecule, a work of art, or a commercial product. The term is also used for copies that closely resemble the original, without claiming to be identical. Also has the same weight and size as original. Replicas have been sometimes sold as originals, a type of fraud. Most replicas have more innocent purposes. Fragile originals need protection, while the public can examine a replica in a museum. Replicas are often manufactured and sold as souvenirs. An inverted replica complements the original by filling its gaps. Sometimes the original never existed. It is logically impossible for there to be a replica of something that never existed. Replicas and reproductions can be related to any form of licensing an image for others to use, whether it is through photos, postcards, prints, miniature or full size copies they represent a resemblance of the original object. Not all incorrectly attributed it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Boarding
Naval boarding action is an offensive tactic used in naval warfare to come up against (or alongside) an enemy marine vessel and attack by inserting combatants aboard that vessel. The goal of boarding is to invade and overrun the enemy personnel on board in order to capture, sabotage or destroy the enemy vessel. While boarding attacks were originally carried out by ordinary sailors who are proficient in hand-to-hand combat, larger warships often deploy specially trained and equipped regular troops such as marines and special forces as boarders. Boarding and close quarters combat had been a primary means to conclude a naval battle since antiquity, until the early modern period when heavy naval guns gained tactical primacy at sea. A cutting out boarding is an attack by small boats, preferably at night and against an unsuspecting, and anchored, target. It became popular in the later 18th century, and was extensively used during the Napoleonic Wars. This heralded the emphas ...

Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone".

Musket
A musket is a muzzle-loaded long gun that appeared as a smoothbore weapon in the early 16th century, at first as a heavier variant of the arquebus, capable of penetrating plate armour. By the mid-16th century, this type of musket gradually disappeared as the use of heavy armour declined, but ''musket'' continued as the generic term for smoothbore long guns until the mid- 19th century. In turn, this style of musket was retired in the 19th century when rifled muskets (simply called rifles in modern terminology) using the Minié ball (invented by Claude-Étienne Minié in 1849) became common. The development of breech-loading firearms using self-contained cartridges (introduced by Casimir Lefaucheux in 1835) and the first reliable repeating rifles produced by Winchester Repeating Arms Company in 1860 also led to their demise. By the time that repeating rifles became common, they were known as simply "rifles", ending the era of the musket. Etymology According to the ...
