APS Underwater Assault Rifle
The APS underwater assault rifle (APS stands for ''Avtomat Podvodny Spetsialnyy'' (Автомат Подводный Специальный) or "Special 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 (Тульский Оружейный Завод, ''Tul'skiy Oruzheynyy Zavod'') in Russia, it is exported by Rosoboronexport. Under water, ordinary bullets are inaccurate and have a very short range. The APS fires a 120 mm (4.75 in) long 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 prot ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ASM-DT Amphibious Rifle
The ASM-DT is a Russian folding-stock underwater firearm. It emerged in the 1990s. History and design The introduction of the APS Underwater Assault Rifle solved the problem of how frogmen guarding a naval base could be armed, but there remained the problem of how to arm naval Spetsnaz combat frogmen when they were deployed on assault missions. These forces required a weapon able to provide them with a level of firepower that would be the same whether they were on the surface or underwater. The APS was of little use out of water, because under those conditions it was inaccurate, with an effective range of only 50 meters. In addition, when it was used out of the water, it wore out quickly, with a barrel life dropping from approximately 2000 rounds to only 180 to 200 rounds. For this reason, the naval Spetsnaz forces often fell back on using the SPP-1 pistol for underwater fighting, and the AK-74 rifle for combat out of water. The commandos thought that this arrangement was unsat ... [...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. While primarily associated with the Soviet Union, it has been used by multiple states throughout the 20th century and onwards. 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 Afghanistan conflict from 1979 onwards. The head of the Afghan bureau of the Inter-Services Intelligence (ISI), the intelligence agency of Pakistan, claimed that America's Central Intelligence Agency (CIA) paid $5,000 for the first AK-74 captured by the Afghan mujahideen during the Afghan-Soviet 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 form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spetsnaz
Spetsnaz are special forces in numerous post-Soviet states. (The term is borrowed from rus, спецназ, p=spʲɪtsˈnas; abbreviation for or 'Special Purpose Military Units'; or .) Historically, the term ''spetsnaz'' referred to the Soviet Union's Spetsnaz GRU, special operations units of the GRU, the main military intelligence service. It also describes task forces of other ministries (such as the Ministry of Internal Affairs' ODON and Ministry of Emergency Situations' special rescue unit) in post-Soviet countries. 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. The 5th Spetsnaz Brigade of Belarus is an example of a non-Russian spetsnaz force. Etymology The Russian abbreviations ''spetsnaz'' and ''osnaz'' are syl ...

Receiver (firearm)
In firearms terminology, 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. The receiver is often made of forged, machined, or stamped steel or aluminium; in addition to these traditional materials, modern science and engineering have introduced polymers and sintered metal powders to receiver construction. Mounting A barrel can be fixed to the receiver using barrel and receiver action threads or similar methods. In US law For the purposes of United States law, the receiver or frame is legally the firearm, and as such it is the controlled part. The definition of which assembly is the legal receiver varies from firearm to firearm, under US law. Generally, the law requ ...

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 pocket knife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knives ( 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 ...
