Naked Soldier (絕色武器) is a 2012 Hong Kong action film directed by Marco Mak and starring Jennifer Tse.
 It is the third installment of the "Naked" series "Naked Killer" (1992) and "Naked Weapon" (2002).
The Bridgeness Slab was found in Bo'ness, Scotland in 1869 on a promontory close to Harbour Road.
 The slab is a Roman Distance slab, marking a portion of the Antonine Wall built by the Second Legion, (Legio II Augusta) and was created around 142 CE.
 It was uncovered during excavations in 1869 on land owned by Henry Mowbray Cadell.
 Cadell offered it to The Society of Antiquaries of Scotland for display in the National Museum of Scotland in Edinburgh if they would provide a copy for display locally.
 In addition to the Latin inscription the original has sculpted panels.
 On the left is a victorious Roman cavalryman with four naked Britons, one being trampled, one running with a spear in his back, one sitting in apparent despair and one of whom is bound and beheaded.
 It has been suggested that the last act was a show of contempt for Gallo-Briton head veneration.
 On the right panel is a depiction of the ritual cleansing of the legion, with a soldier at the rear carrying the vexillum, or cavalry flag, of Legio II Augusta.
 The inscription records the building of 4,655 paces of the Antonine Wall.
The matchlock was the first mechanism invented to facilitate the firing of a hand-held firearm.
 Before this, firearms (like the hand cannon) had to be fired by applying a lit match (or equivalent) to the priming powder in the flash pan by hand; this had to be done carefully, taking most of the soldier's concentration at the moment of firing, or in some cases required a second soldier to fire the weapon while the first held the weapon steady.
 Adding a matchlock made the firing action simple and reliable by a single soldier, allowing him to keep both hands steadying the gun and eyes on the target while firing.
Tracer ammunition (tracers) are bullets or cannon caliber projectiles that are built with a small pyrotechnic charge in their base.
 Ignited by the burning powder, the pyrotechnic composition burns very brightly, making the projectile trajectory visible to the naked eye during daylight, and very bright during nighttime firing.
 This enables the shooter to make aiming corrections without observing the impact of the rounds fired and without using the sights of the weapon.
 Tracer fire can also be used to signal to other shooters where to concentrate their fire during battle.
And babies (December 26, 1969) is an iconic anti-Vietnam War poster.
 It is a famous example of "propaganda art" from the Vietnam conflict that uses the now infamous color photograph of the My Lai Massacre taken by U.S. combat photographer Ronald L. Haeberle on March 16, 1968.
 It shows about a dozen dead and partly naked South Vietnamese women and babies in contorted positions stacked together on a dirt road, killed by U.S. forces.
 The picture is overlaid in semi-transparent blood-red lettering that asks along the top "Q. And babies?"
, and at the bottom answers "A. And babies."
 The quote is from a Mike Wallace CBS News television interview with U.S. soldier Paul Meadlo, who participated in the massacre.
 The lettering was sourced from "The New York Times", which printed a transcript of the Meadlo interview the day after.
E.H. Roelfzema is the pen name of Erik Hazelhoff Roelfzema Jr. (February 17, 1947, The Hague - February 11, 2010, Kockengen), Dutch artist, writer, poet, lyricist and musician.
 In his art he used encaustic techniques, as well as polymer resin (glass panels), and monomer resin (embeddings).
 He travelled extensively, and from 1970 until 1990 he lived in Ahualoa, Hawaii, working as a farmer and fisherman, and surfing.
 He returned to the Netherlands in 1990 and married photographer Patricia Steur.
 His father was writer of the book "Soldier of Orange", which was made into a film directed by Paul Verhoeven and starring Rutger Hauer.
 Musical collaborations include those with Roll, and Pizza Delivery Boys.
 Dutch rock band Golden Earring recorded numerous lyrics by E.H. Roelfzema, including the band's signature tunes: "The Naked Truth".
The lance is a pole weapon or spear designed to be used by a mounted warrior or cavalry soldier (lancer).
 During the periods of classical and medieval warfare, it evolved into being the leading weapon in cavalry charges, and was unsuited for throwing or for repeated thrusting, unlike similar weapons of the spear/javelin/pike family typically used by infantry.
 Lances were often equipped with a vamplate – a small circular plate to prevent the hand sliding up the shaft upon impact.
 Though best known as a military and sporting weapon carried by European knights, the use of lances was widespread throughout Asia, the Middle East and North Africa wherever suitable mounts were available.
 As a secondary weapon, lancers of the medieval period also bore swords, axes or maces for hand-to-hand combat, since the lance was often a one-use-per-engagement weapon; assuming the lance survived the initial impact intact, it was (depending on the lance) usually too long, heavy and slow to be effective against opponents in a melee.
The Advanced Combat Rifle (ACR) was a United States Army program, started in 1986, to find a replacement for the M16 assault rifle.
 Under the stress of battle the average soldier with an M16 could guarantee hitting a target at 45 meters, but hit probability was reduced to one out of ten shots on target by 220 meters.
 Because of this, The ACR program was initiated in the late 1980s to create a weapon that could double the hit probability.
 The ACR program was preceded by older programs such as the Special Purpose Individual Weapon.
 The program ended in 1990 after an expenditure of approximately US$300 million.
Naked Weapon (赤裸特工) is a 2002 Hong Kong action-thriller film directed by action choreographer Tony Ching and starring Maggie Q, Anya Wu and Daniel Wu.
Big Boss is one of the central characters in the "Metal Gear" video game series.
 He was introduced in the original "Metal Gear" games for the MSX2 as the commanding officer and subsequent nemesis of Solid Snake.
 He is later featured as Naked Snake, the protagonist of "Metal Gear Solid" prequels where he is initially depicted as an American Special Forces Operator and decorated war hero until political manipulations cause him to be disillusioned and start his own private mercenary company.
 Big Boss's character has been praised by video game publications for his role as a villain as well for his relationship with Solid Snake.
 As the series' chronology progressed, his exact allegiance and motivations became increasingly complex; his first appearances are depicted as a traitor dreaming of a world of perpetual war, but subsequent appearances have revealed him to be a key figure in an ideological dispute that shaped the latter half of the twentieth century and a man whose conscience was disturbed by the attitude of leaders towards soldiers, prompting his decision to become a soldier of fortune and Venom Snake's mental template.
