SIG Sauer M18
The SIG Sauer M17 and M18 are service pistols derived from the SIG Sauer P320 in use with the United States Armed Forces. On January 19, 2017, the United States Army announced that a customized version of SIG Sauer's P320 had won the Army's XM17 Modular Handgun System competition. The full-sized model was designated the M17, and the shorter length carry model, the M18. The guns have subsequently been adopted by the Army, Navy, Marine Corps, Air Force, and Space Force. The pistol replaces the Beretta M9, as well as several other handguns across the services. There are two color variants, coyote brown and black, for both the M17 and M18, though almost all have been produced in brown. Modular Handgun System competition When the requirements were formulated for a new handgun for the U.S. Army, one of the tenets of the proposal was that an existing model handgun was desired to fulfill the requirements laid out in the Modular Handgun System Request for Proposal, known as the XM17 Proc ...

USAF
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fireteam
A fireteam or fire team is a small military sub-subunit of infantry designed to optimize "bounding overwatch" and "fire and movement" tactical doctrine in combat. Depending on mission requirements, a typical fireteam consists of four or fewer members: an automatic rifleman, a grenadier, a rifleman, and a designated team leader. The role of each fireteam leader is to ensure that the fireteam operates as a cohesive unit. Two or three fireteams are organized into a section or squad in co-ordinated operations, which is led by a squad leader. Historically, nations with effective fireteam organization have had a significantly better performance from their infantry units in combat than those limited to operations by traditionally larger units. US Army doctrine recognizes the fire team, or crew, as the smallest military organization while NATO doctrine refers to this level of organization simply as team. Fireteams are the most basic organization upon which modern infantry units are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squad
In military terminology, a squad is among the smallest of military organizations and is led by a non-commissioned officer. NATO and US doctrine define a squad as an organization "larger than a team, but smaller than a section." while US Army doctrine further defines a squad as a "small military unit typically containing two or more fire teams." In US usage, a squad consists of eight to fourteen soldiers, and may be further subdivided into fireteams. Organization NATO The standard NATO symbol for a ''squad'' consists of one single dot (●) placed above a framed unit icon. United States United States Army Historically, a "squad" in the US Army was a sub-unit of a section, consisting of from as few as two soldiers to as many as 12 and was originally used primarily for drill and administrative purposes (e.g., billeting, messing, working parties, etc.). The smallest tactical sub-unit being the section, which was also known as a half-platoon (the platoon itself being a half com ...

Tritium Sight
Tritium radioluminescence is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light. Tritium emits electrons through beta decay and, when they interact with a phosphor material, light is emitted through the process of phosphorescence. The overall process of using a radioactive material to excite a phosphor and ultimately generate light is called radioluminescence. As tritium illumination requires no electrical energy, it has found wide use in applications such as emergency exit signs, illumination of wristwatches, and portable yet very reliable sources of low intensity light which won't degrade human night vision. Gun sights for night use and small lights (which need to be more reliable than battery powered lights, yet not interfere with night vision or be bright enough to easily give away one's location) used mostly by military personnel fall under the latter application. History Tritium was found to be an ideal energy source for self-luminous com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunsmith
A gunsmith is a person who repairs, modifies, designs, or builds guns. The occupation differs from an armorer, who usually replaces only worn parts in standard firearms. Gunsmiths do modifications and changes to a firearm that may require a very high level of craftsmanship, requiring the skills of a top-level machinist, a very skilled woodworker, and even an engineer. Gunsmiths perform factory-level repairs and renovations to restore a well-used or deteriorated firearms to new condition. They may make alterations to adapt sporting guns to better fit the individual shooter that may require extensive modifications to the firearm's stocks and metal parts. Repairs and redesigns may require fabrication and fitting of unavailable parts and assemblies constructed by smiths themselves. Gunsmiths may also renew metal finishes or apply decorative carvings or engravings to guns. Many gun shops offer gunsmithing service on the premises. Overview Gunsmiths may be employed in: *factories by fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Screw Drives
At a minimum, a screw drive is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. The following heads are categorized based on frequency, with some of the less-common drives being classified as "tamper-resistant." Most heads come in a range of sizes, typically distinguished by a number, such as "Phillips #00". These sizes do not necessarily describe a particular dimension of the drive shape, but rather are arbitrary designations. Slotted drives Slot Slot screw drives have a single horizontal indentation (the ''slot'') in the fastener head and is driven by a "common blade" or flat-bladed screwdriver. This form was the first type of screw drive to be developed, and for centuries, it was the simplest and cheapest to make. Additionally, it is unique compared to other common drives, due to it being straightforward to manufacture the slot h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Vapor Deposition
Physical vapor deposition (PVD), sometimes called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings on substrates including metals, ceramics, glass, and polymers. PVD is characterized by a process in which the material transitions from a condensed phase to a vapor phase and then back to a thin film condensed phase. The most common PVD processes are sputtering and evaporation. PVD is used in the manufacturing of items which require thin films for optical, mechanical, electrical, acoustic or chemical functions. Examples include semiconductor devices such as thin-film solar cells, microelectromechanical devices such as thin film bulk acoustic resonator, aluminized PET film for food packaging and balloons, and titanium nitride coated cutting tools for metalworking. Besides PVD tools for fabrication, special smaller tools used mainly for scientific purposes have been developed. The source material i ...
