APS Underwater Assault Rifle
The APS underwater assault rifle () is an underwater firearm designed by the Soviet Union in the early 1970s. It was adopted in 1975. Made by the Tula Arms Plant () in Russia, it is exported by Rosoboronexport. Under water, ordinary bullets are inaccurate and have a very short range. The APS fires a , 5.66 mm calibre steel bolt specially designed for this weapon. Its magazine holds 26 rounds. The APS's barrel is not rifled; the fired projectile is kept in line by hydrodynamic effects; as a result, the APS is somewhat inaccurate when fired out of water. The APS has a longer range and more penetrating power than spearguns. This is useful in such situations such as shooting an opposing diver through a reinforced dry suit, a protective helmet (whether air-holding or not), thick tough parts of breathing sets and their harnesses, and the plastic casings and transparent covers of some small underwater vehicles. The APS is more powerful than a pistol, but is bulkier, heavier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diver Propulsion Vehicle
A diver propulsion vehicle (DPV), also known as an underwater propulsion vehicle, sea scooter, underwater scooter, or swimmer delivery vehicle (SDV) by armed forces, is an item of diving equipment used by scuba divers to increase range underwater. Range is restricted by the amount of breathing gas that can be carried, the rate at which that breathing gas is consumed, and the battery power of the DPV. Time limits imposed on the diver by decompression requirements may also limit safe range in practice. DPVs have recreational, scientific and military applications. DPVs include a range of configurations from small, easily portable scooter units with a small range and low speed, to faired or enclosed units capable of carrying several divers longer distances at higher speeds. The earliest recorded DPVs were used for military purposes during World War II and were based on torpedo technology and components. Structure A DPV usually consists of a pressure-resistant watertight casing c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AK-74
The AK-74 ( Russian: , tr. ''Avtomat Kalashnikova obraztsa 1974 goda'', lit. 'Kalashnikov assault rifle model 1974') is an assault rifle designed by small arms designer Mikhail Kalashnikov in 1974 as a successor to the AKM. While primarily associated with the Soviet Union, it has been used by many countries since the 1970s. It is chambered for the 5.45×39mm cartridge, which replaced the 7.62×39mm cartridge of Kalashnikov's earlier automatic weapons for the Soviet Armed Forces. The rifle first saw service with Soviet forces in the Soviet–Afghan War from 1979. The head of the Afghan bureau of the Inter-Services Intelligence (ISI), the intelligence agency of Pakistan, claimed that the American Central Intelligence Agency (CIA) paid $5,000 for the first AK-74 captured by the Afghan mujahideen during the war. , most countries of the former Soviet Union use the rifle. Licensed copies were produced in Bulgaria (AK-74, AKS-74 and AKS-74U), and in the former East Germany ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spetsnaz
SpetsnazThe term is borrowed from rus, спецназ, p=spʲɪtsˈnas; abbreviation for or 'Special Purpose Military Units'; or () are special forces in many post-Soviet states. Historically, this term referred to the Soviet Union's Spetsnaz GRU, special operations units of the GRU (Soviet Union), Main Intelligence Directorate of the Soviet General Staff (GRU). Today it refers to special forces branches and task forces subordinate to ministries including defence, internal affairs, or emergency situations in countries that have inherited their special purpose units from the Chronology of Soviet secret police agencies, now-defunct Soviet security agencies. As ''spetsnaz'' is a Russian term, it is typically associated with the special units of Russia, but other post-Soviet states often refer to their special forces units by the term as well, since these nations also inherited their special purpose units from the now-defunct Soviet security agencies.

Receiver (firearm)
In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing for internal action components such as the hammer, bolt or breechblock, firing pin and extractor, and has threaded interfaces for externally attaching ("receiving") components such as the barrel, stock, trigger mechanism and iron/optical sights. Some firearm designs, such as the AR-15 platform, feature receivers that have 2 separate sub-assemblies called the upper receiver which houses the barrel/trunnion, bolt components etc and the lower receiver (Trigger Mechanism Housing in some cases) that holds the fire control group, pistol grip, selector, stock etc. The receiver is often made of forged, machined, or stamped steel or aluminium. Apart from these traditional materials, modern techniques have introduced polymer and sintered metal powder receivers to the market. Mounting A barrel may typically be affixed to a firearm receiver usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kalashnikov Rifle
Kalashnikov rifles (), also known as the AK platform, AK rifles, or simply the AK, are a family of assault rifles based on Mikhail Kalashnikov's original design. They are officially known in Russian as ''avtomat Kalashnikova'' (), and informally as ''kalash'' in Russian. They were originally manufactured in the Soviet Union by Kalashnikov Concern (formerly Izhmash). Rifles similar to the Kalashnikov and its Soviet variants were later produced in many countries friendly to the Soviet Bloc, with rifles based on its design such as the Galil ACE and the INSAS also being produced. The Kalashnikov is one of the most widely used firearm A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual.

Knives
A knife (: knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin. Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocketknife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knife ( butter knives and steak knives), weapons (daggers or switchblades), knives for throwing or juggli ...

Anti-frogman Techniques
Defenses against swimmer incursions are security methods developed to protect watercraft, ports and installations, and other sensitive resources in or near vulnerable waterways from potential threats or intrusions by swimmers or scuba divers. Risks and threats The need for military underwater security was demonstrated in World War II by the achievements of frogmen against armed forces facilities such as the Italian frogman actions in WWII. Since the late 1950s, the increasing demand for and availability of sophisticated scuba diving equipment has also created concerns about protecting valuable underwater archaeology sites and shellfish fishing stocks. The 12 October 2000 USS Cole bombing was not carried out by underwater divers, but did bring renewed attention to the vulnerability they present for naval ships. Divers can swim 100 to 200 yards in about three minutes, and large sonar ranges would be required around ships for security forces to detect underwater swimmers in time t ...
