The M242 Bushmaster is a 25 mm chain-driven autocannon. It is used extensively by the U. S. military, as well as by NATO's and some other nations' forces in ground combat vehicles, such as the Bradley fighting vehicle and various watercraft. The weapon was designed and manufactured by Hughes Ordnance in Culver City, acquired by McDonnell Douglas, it is an externally powered, chain-driven, single-barrel weapon which may be fired in semi-automatic, burst, or automatic modes. It has dual-feed capability; the term "chain gun" derives from the use of a roller chain that drives the bolt forth. The gun can destroy armored vehicles and aerial targets, it can suppress enemy positions such as exposed troops, dug-in positions, occupied built-up areas. The standard rate of fire is 200 rounds per minute; the weapon has an effective range of 3,000 metres, depending on the type of ammunition used. With over 10,000 units sold worldwide, it is one of the most successful modern autocannons; the Bushmaster project started as an offshoot of the US Army's MICV-65 program, attempting to introduce a new infantry fighting vehicle to replace their existing M113s.
Part of this program called for a new scout vehicle to replace the M114, a parallel development taking place under the XM800 Armored Reconnaissance Scout Vehicle. Both the XM800 and the cavalry version of the XM701 MICV vehicles were armed with the M139, a US-built version of the Hispano-Suiza HS.820 20 mm autocannon. During the testing phase, the Army rejected the XM701 and started work on a newer design known as the XM723. Soon after the XM800 was rejected; this led to the combination of the two programs, moving the scout role to the cavalry version of the XM723. At the same time, the M139 proved to be disappointing and a contract for a new weapon to replace it started as a competitive development in 1972 at Ford Aeronutronic Division and Hughes Helicopters Ordnance Division under the Summa Corporation as the Vehicle Rapid-Fire Weapons System-Successor, or VRFWS-S; this was a power-driven gun firing similar 20mm ammunition as the HS.820, the power-driven mechanism would ensure operation in the case of a misfire.
Progress on the VRFWS-S was slow, resulted in a switch to a much more powerful 25 mm round. Similar delays in the MICV program meant the ultimate vehicles descending from their efforts, the M2/M3 Bradley Fighting Vehicle, did not enter production until 1981, by which point the Bushmaster had matured. Since 1990, there have been several enhancements made upon the weapon, resulting in the Enhanced 25 mm gun. To date, more than 10,500 weapons are in service. One of the major reasons for this popularity is the reliable nature of the weapon, it has a rating of 22,000 mean rounds between failure, much higher than many comparable devices. Unlike most automatic firearms, the M242 does not depend on gas or recoil to actuate its firing system. Instead, it uses a 1 hp DC motor, positioned in the receiver to drive the chain and dual-feed system; this system uses sprockets and extractor grooves to feed, fire and eject rounds. A system of clutches provides for an alternate sprocket to engage and thus allows the gunner to switch between armor-piercing and high-explosive rounds.
The weapon assembly consists of three parts: the barrel assembly, the feeder assembly, the receiver assembly. The three-part structure makes it possible for a two-person team to install or remove the system despite its considerable total weight; the M242 weapon system has both electrical and manual fire control and can be operated electrically or manually. In doing so, the gunner can choose from three rates of fire: Single Shot Semi-Automatic, in which the gunner can shoot as fast as the trigger can be operated, limited only by the electrical drive speed. A wide range of ammunition has been developed for this weapon, providing it with the capability to defeat the majority of armored vehicles it is to encounter, up to and including some light tanks; the ammunition used in the M242 may be used in a variety of weapons such as the GAU-12 Equalizer, the French Giat M811, or the Swiss Oerlikon KBA weapon system. It has the capability to fire U. S. manufactured ammunition as well as the NATO equivalents thereof.
Though, it fires six types of rounds: the M791, M792, M793, M910, MK210, M919. M791 Armor-piercing discarding sabot with Tracer 5.7 million rounds produced The APDS-T penetrates armored vehicles, self-propelled artillery, aerial targets such as helicopters and various slow-moving, fixed-wing aircraft. M792 High Explosive Incendiary with Tracer and Self Destruct 5.5 million rounds produced The HEI-T can destroy unarmored vehicles and helicopters and suppress antitank missile positions and enemy squads out to a maximum effective range of 2,200 meters. M793 Target Practice with Tracer 11.5 million rounds produced The TP-T cartridge is a fixed-type, percussion-primed training round that matches the High Explosive Incendiary with Tracer round ballistically. The TP-T's tracer is visible out to 2,000 meters, the round has a maximum effective range of 1,600 meters. M910 Target Practice Discarding Sabot with Tracer
War in Afghanistan (2001–present)
The War in Afghanistan, code named Operation Enduring Freedom – Afghanistan and Operation Freedom's Sentinel, followed the United States invasion of Afghanistan of 7 October 2001. The U. S. was supported by the United Kingdom and Australia and by a coalition of over 40 countries, including all NATO members. The war's public aims were to dismantle al-Qaeda and to deny it a safe base of operations in Afghanistan by removing the Taliban from power. Since the initial objectives were completed at the end of 2001, the war involves U. S. and allied Afghan government troops battling Taliban insurgents. The War in Afghanistan is the longest war in U. S. history. Following the September 11 attacks in 2001 on the U. S. which President George W. Bush blamed on Osama bin Laden, living or hiding in Afghanistan and had been wanted since 1998, President Bush demanded that the Taliban, who were de facto ruling the country, hand over bin Laden; the Taliban declined to extradite him unless they were provided clear evidence of his involvement in the attacks, which the U.
S. dismissed as a delaying tactic and on 7 October 2001 launched Operation Enduring Freedom with the United Kingdom. The two were joined by other forces, including the Northern Alliance – the Afghan opposition, fighting the Taliban in the ongoing civil war since 1996. By December 2001, the Taliban and their al-Qaeda allies were defeated in the country, at the Bonn Conference new Afghan interim authorities elected Hamid Karzai to head the Afghan Interim Administration; the United Nations Security Council established the International Security Assistance Force to assist the new authority with securing Kabul, which after a 2002 loya jirga became the Afghan Transitional Administration. A nationwide rebuilding effort was made following the end of the totalitarian Taliban regime. In the popular elections of 2004, Karzai was elected president of the country, now named the Islamic Republic of Afghanistan. NATO became involved in ISAF in August 2003, that year assumed leadership of it. At this stage, ISAF included troops from 43 countries with NATO members providing the majority of the force.
One portion of U. S. forces in Afghanistan operated under NATO command. S. command. Following defeat in the initial invasion, the Taliban was reorganized by its leader Mullah Omar, launched an insurgency against the Afghan government and ISAF in 2003. Though outgunned and outnumbered, insurgents from the Taliban - and to a lesser extent Hezb-e-Islami Gulbuddin and other groups - waged asymmetric warfare with guerrilla raids and ambushes in the countryside, suicide attacks against urban targets, turncoat killings against coalition forces; the Taliban exploited weaknesses in the Afghan government to reassert influence across rural areas of southern and eastern Afghanistan. From 2006 the Taliban made significant gains and showed an increased willingness to commit atrocities against civilians – ISAF responded by increasing troops for counter-insurgency operations to "clear and hold" villages. Violence escalated from 2007 to 2009. Troop numbers began to surge in 2009 and continued to increase through 2011 when 140,000 foreign troops operated under ISAF and U.
S. command in Afghanistan. Of these 100,000 were from the U. S. On 1 May 2011, United States Navy SEALs killed Osama bin Laden in Pakistan. NATO leaders in 2012 commended an exit strategy for withdrawing their forces, the United States announced that its major combat operations would end in December 2014, leaving a residual force in the country. In October 2014, British forces handed over the last bases in Helmand to the Afghan military ending their combat operations in the war. On 28 December 2014, NATO formally ended ISAF combat operations in Afghanistan and transferred full security responsibility to the Afghan government; the NATO-led Operation Resolute Support was formed the same day as a successor to ISAF. As of May 2017, over 13,000 foreign troops remain in Afghanistan without any formal plans to withdraw, continue their fight against the Taliban, which remains by far the largest single group fighting against the Afghan government and foreign troops. Tens of thousands of people have been killed in the war.
Over 4,000 ISAF soldiers and civilian contractors, over 62,000 Afghan national security forces were killed, as well as over 31,000 civilians and more Taliban. Afghanistan's political order began to break down with the overthrow of King Zahir Shah by his distant cousin Mohammed Daoud Khan in a bloodless 1973 Afghan coup d'état. Daoud Khan had served as prime minister since 1953 and promoted economic modernization, emancipation of women, Pashtun nationalism; this was threatening to neighboring Pakistan, faced with its own restive Pashtun population. In the mid-1970s, Pakistani Prime Minister Zulfikar Ali Bhutto began to encourage Afghan Islamist leaders such as Burhanuddin Rabbani and Gulbuddin Hekmatyar, to fight against the regime. In 1978, Daoud Khan was killed in a coup by Afghan's Communist Party, his former partner in government, known as the People's Democratic Party of Afghanistan; the PDPA pushed for a socialist transformation by abolishing arranged marriages, promoting mass literacy and reforming land ownership.
This provoked opposition across rural areas. The PDPA's crackdown was met including Ismail Khan's Herat Uprising; the PDPA was beset by internal leadership differences and was weakened by an internal coup on 11 September 1979 when Hafizullah Amin ousted Nur Muhammad Tara
An airdrop is a type of airlift, developed during World War II to resupply otherwise inaccessible troops, who themselves may have been airborne forces. In some cases, it is used to refer to the airborne assault itself. Early airdrops were conducted by pushing padded bundles from aircraft. Small crates with parachutes were pushed out of the aircraft's side cargo doors. Cargo aircraft were designed with rear access ramps, lowerable in flight, that allowed large platforms to be rolled out the back; as aircraft grew larger, the U. S. Air Force and Army developed low-level extraction, allowing tanks and other large supplies to be delivered, such as the M551 Sheridan or BMD-3. Propaganda leaflets are a common item to airdrop; the airdropping of weapons evolved to the concept of having the payload itself as one massive bomb. The 15,000 pound BLU-82, nicknamed the "Daisy Cutter" for its ability to turn a dense forest into a helicopter landing zone in a single blast, was used in Vietnam and in Afghanistan.
The 22,600 pound GBU-43/B, nicknamed the "Mother Of All Bombs", was deployed to the Persian Gulf for The Iraq War. These palletized airdropped weapons are used by cargo aircraft like the C-130 or C-17 in the traditional role of a bomber aircraft. In peacekeeping operations or humanitarian aid situations and medical supplies are airdropped from the United Nations and other aircraft; the type of airdrop refers to the way. There are several types of airdrop, each type may be performed via several methods. Low-Velocity Airdrop is the delivery of a load involving parachutes that are designed to slow down the load as much as possible to ensure it impacts the ground with minimal force; this type of airdrop is used for larger items such as vehicles. High-Velocity Airdrop is the delivery of a load involving a parachute meant to stabilize its fall; the parachute will slow the load to some degree but not to the extent of a Low-Velocity airdrop as High-Velocity airdrops are used for durable items like MREs.
LAPES is a variation of an HV drop where the aircraft completes a touch-and-go type pattern and the load is ejected at an low altitude. This is shown in the photo of the C-130 airdropping a tank. Free Fall Airdrop is an airdrop with no parachute at all. A common example of this type of airdrop is the delivery of leaflets used in psychological warfare; the method of airdrop refers to the way. There are three main methods of airdrop used in military operations. Auto Extraction airdrops use an extraction parachute to pull the load out of the aircraft end of the airplane. In this method, an extraction parachute is deployed behind the aircraft which pulls the load out and cargo parachutes are deployed to slow the load. Extraction drops are Low-Velocity airdrops, with rare exceptions. Manual Extraction airdrops, where the load is physically pushed out by a specially trained crew of up to four people. Gravity airdrops use gravity in the sense that the attitude of the aircraft at the time of the drop causes the load to roll out of the plane like a sled down a hill.
The most common use of a gravity airdrop is for the Container Delivery System bundle. Door bundle drops are the simplest of airdrop methods. In a door bundle airdrop, the Loadmaster pushes out the load at the appropriate time. Bomber aircraft were sometimes used to drop supplies, using special supply canisters that were compatible with the aircraft's bomb attachment system. During World War II, German bomber aircraft dropped containers called Versorgungsbomben to supply friendly troops on the ground; the British equivalent was the CLE Canister that could carry up to 600 pounds of supplies or weapons. Notably and American bombers air-dropped weapons to the Polish Home Army during the Warsaw Uprising in 1944; the Western Allies used bombers to drop food on the Netherlands to help feed civilians who were in danger of starvation in the Dutch famine of 1944. The Anglo-American Operations Manna and Chowhound took place with Germany's agreement not to fire on the aircraft taking part. 395 Air Despatch Troop RLC Airborne leaflet propaganda Airbridge Airmail Delivery drone Feeding altcoins Joint Precision Airdrop System Loadmaster Paratrooper Winged tank Technical Order 13C7-1-11 Airdrop of Supplies and Equipment: Rigging Containers.

The AKM is a 7.62mm assault rifle designed by Mikhail Kalashnikov. It is a common modernized variant of the AK-47 rifle developed in the 1940s. Introduced into service with the Soviet Army in 1959, the AKM is the most ubiquitous variant of the entire AK series of firearms and it has found widespread use with most member states of the former Warsaw Pact and its African and Asian allies as well as being exported and produced in many other countries; the production of these rifles was carried out at both Izhmash. It was replaced in Soviet frontline service by the AK-74 in the late 1970s, but remains in use worldwide; the AKM is an assault rifle using the 7.62×39mm Soviet intermediate cartridge. It is gas operated with a rotating bolt; the AKM is capable of selective fire, firing either single shots or automatic at a cyclic rate of 600 rounds/min. Despite being replaced in the late 1970s by the AK-74, the AKM is still in service in some Russian Army reserve and second-line units and several east European countries.
The GRAU designated the AKM as the 6P1 assault rifle. Compared with the AK-47, the AKM features detail improvements and enhancements that optimized the rifle for mass production. Notably, the AK-47's milled steel receiver was replaced by a U-shaped steel stamping; as a result of these modifications, the AKM’s weight was reduced by ≈ 1 kg, the accuracy during automatic fire was increased and several reliability issues were addressed. The AK-47's chrome-lined barrel was retained, a common feature of Soviet weapons which resists wear and corrosion under harsh field conditions and near-universal Eastern Bloc use of corrosively primed ammunition; the AKM’s receiver is stamped from a smooth 1.0 mm sheet of steel, compared with the AK-47 where the receiver was machined from heavier gauge steel. A rear stock trunnion and forward barrel trunnion are fastened to the U-shaped receiver using rivets; the receiver housing features a rigid tubular cross-section support that adds structural strength. Guide rails that assist the bolt carrier’s movement which incorporates the ejector are installed inside the receiver through spot welding.
As a weight-saving measure, the stamped receiver cover is of thinner gauge metal than that of the AK-47. In order to maintain strength and durability it employs both longitudinal and latitudinal reinforcing ribs; the forward barrel trunnion has a non-threaded socket for the barrel and a transverse hole for a pin that secures the barrel in place. On some models the rear trunnion has two extended mounting arms on both sides that support the buttstock; the AKM's barrel is pinned. Additionally the barrel has horizontal guide slots that help align and secure the handguards in place. To increase the weapon’s accuracy during automatic fire, the AKM was fitted with a slant cut muzzle brake that helps redirect expanding propellant gases upward and to the right during firing, which mitigates the rise of the muzzle during an automatic burst when held by a right-handed firer; the muzzle brake is threaded on to the end of the barrel with a left-hand thread. Not all AKMs had slant muzzle brakes. Most AKMs with muzzle nuts were older production weapons.
The AKM's slant brake can be used on the AK-47, which had a simple nut to cover the threads. The gas block in the AKM does not have a cleaning rod capture or sling loop but is instead fitted with an integrated bayonet support collar that has a cleaning rod guide hole; the forward sling loop was relocated to the front handguard retainer cap. The handguard retainer has notches that determine the position of the handguards on the barrel; the AKM's laminated wood handguards have lateral grooves. Gas relief ports that alleviate gas pressure in the piston cylinder were moved forward to the gas block and placed in a radial arrangement; the AKM’s bolt carrier is lighter in weight and has some minor differences in its shape. The buttstock, lower handguard and upper heatguard are manufactured from birch plywood laminates like the model AK-47 furniture; such engineered woods are stronger and resist warping better than the conventional one-piece patterns, do not require lengthy maturing, are cheaper. The wooden buttstock used in the AKM is further hollowed in order to reduce weight and is longer and straighter than that of the AK-47, which assists accuracy for subsequent shots during rapid and automatic fire.
The wooden stock houses the issued cleaning kit, a small diameter metal tube with a twist lock cap. The kit contains the cleaning jag to which a piece of cloth material is wrapped around and dipped into cleaning solution, it contains a pin punch, an assembly pin to hold the trigger and rate reducer together while putting these back into the receiver after cleaning the weapon, a barrel brush. The kit is secured inside the butt stock via a spring-loaded trap door in the stock's pressed sheet metal butt cap; the AKM uses a modified return spring mechanism, which replaces the single recoil spring guide rod with a dual “U”-shaped wire guide. The AKM has a modified trigger assembly, equipped with a hammer-release delaying device (insta
Armoured fighting vehicle
An armoured fighting vehicle is an armed combat vehicle protected by armour combining operational mobility with offensive and defensive capabilities. AFVs can be tracked. Main battle tanks, armoured cars, armoured self-propelled guns, armoured personnel carriers are all examples of AFVs. Armoured fighting vehicles are classified according to their intended role on the battlefield and characteristics; the classifications are not absolute. For example lightly armed armoured personnel carriers were superseded by infantry fighting vehicles with much heavier armament in a similar role. Successful designs are adapted to a wide variety of applications. For example, the MOWAG Piranha designed as an APC, has been adapted to fill numerous roles such as a mortar carrier, infantry fighting vehicle, assault gun; the concept of a mobile and protected fighting unit has been around for centuries. Armoured fighting vehicles were not possible until internal combustion engines of sufficient power became available at the start of the 20th century.
Modern armoured fighting vehicles represent the realization of an ancient concept - that of providing troops with mobile protection and firepower. Armies have deployed war cavalries with rudimentary armour in battle for millennia. Use of these animals and engineering designs sought to achieve a balance between the conflicting paradoxical needs of mobility and protection. Siege engines, such as battering rams and siege towers, would be armoured in order to protect their crews from enemy action. Polyidus of Thessaly developed a large movable siege tower, the helepolis, as early as 340 BC, Greek forces used such structures in the Siege of Rhodes; the idea of a protected fighting vehicle has been known since antiquity. Cited is Leonardo da Vinci's 15th-century sketch of a mobile, protected gun-platform; the machine was to be mounted on four wheels which would be turned by the crew through a system of hand cranks and cage gears. Leonardo claimed: "I will build armored wagons which will be invulnerable to enemy attacks.
There will be no obstacle which it cannot overcome." Modern replicas have demonstrated that the human crew would have been able to move it over only short distances. Hussite forces in Bohemia developed war wagons - medieval weapon-platforms - around 1420 during the Hussite Wars; these heavy wagons were given protective sides with firing slits. Heavy arquebuses mounted on wagons were called arquebus à croc; these carried a ball of about 3.5 ounces. The first modern AFVs were armed cars, dating back to the invention of the motor car; the British inventor F. R. Simms designed and built the Motor Scout in 1898, it was the first armed, petrol-engine powered vehicle built. It consisted of a De Dion-Bouton quadricycle with a Maxim machine gun mounted on the front bar. An iron shield offered some protection for the driver from the front, but it lacked all-around protective armour; the armoured car was the first modern armoured fighting vehicle. The first of these was the Simms' Motor War Car, designed by Simms and built by Vickers, Sons & Maxim in 1899.
The vehicle had Vickers armour 6 mm thick and was powered by a four-cylinder 3.3-litre 16 hp Cannstatt Daimler engine giving it a maximum speed of around 9 miles per hour. The armament, consisting of two Maxim guns, was carried in two turrets with 360° traverse. Another early armoured car of the period was the French Charron, Girardot et Voigt 1902, presented at the Salon de l'Automobile et du cycle in Brussels, on 8 March 1902; the vehicle was equipped with a Hotchkiss machine gun, with 7 mm armour for the gunner. Armoured cars were first used in large numbers on both sides during World War I as scouting vehicles. In 1903, H. G. Wells published the short story "The Land Ironclads," positing indomitable war machines that would bring a new age of land warfare, the way steam-powered ironclad warships had ended the age of sail. Wells' literary vision was realized in 1916, amidst the pyrrhic standstill of the Great War, the British Landships Committee, deployed revolutionary armoured vehicles to break the stalemate.
The tank was envisioned as an armoured machine that could cross ground under fire from machine guns and reply with its own mounted machine guns and cannons. These first British heavy tanks of World War I moved on caterpillar tracks that had lower ground pressure than wheeled vehicles, enabling them to pass the muddy, pocked terrain and slit trenches of the Battle of the Somme; the tank proved successful and, as technology improved. It became a weapon that could cross large distances at much higher speeds than supporting infantry and artillery; the need to provide the units that would fight alongside the tank led to the development of a wide range of specialised AFVs during the Second World War. The Armoured personnel carrier, designed to transport infantry troops to the frontline, emerged towards the end of World War I. During the first actions with tanks, it had become clear that close contact with infantry was essential in order to secure ground won by the tanks. Troops on foot were vulnerable to enemy fire, but they could not be transported
Eight-wheel drive notated as 8WD or 8×8, is a drivetrain configuration that allows all eight wheels of an eight-wheeled vehicle to be drive wheels simultaneously. Unlike four-wheel drive drivetrains, the configuration is confined to heavy-duty off-road and military vehicles, such as all-terrain vehicles, armored vehicles, prime movers. Other types of smaller 8x8 vehicles include such things as the Argocat; when such a vehicle only has eight wheels by definition all are driven. When it has twelve – with two pairs of ganged "dual" wheels on each rear axle – all are driven but the 8×8 designation remains. On the Sterling T26 for example, the two front axles can be fitted with ganged "dual" wheels. For most military applications where traction/mobility are considered more important than payload capability, single wheels on each axle are the norm. On some vehicles recovery trucks or heavy tractor units, the rear two axles will have wider single tires than the front two axles. Heavy hauler and ballast tractor 8×8s have had a long history as prime movers both in the military, commercially in logging and heavy equipment hauling both on- and off-road.
Most eight-wheel drive trucks have two forward axles and two at the rear, with only the front pair steering. And single front axle and three rear are seen, an example being the Oshkosh M1070 tank transporter. In such configurations, the front and rear axle steer. Other set ups include that of the ZIL-135. Many wheeled armored vehicles have an 8x8 driveline, on these the axles are more evenly spaced. Latest generation 8x8 wheeled armored vehicles have steering on the rearmost axle to improve mobility in urban and confined situations. In the case of both truck and armored vehicle applications, drive may be limited to the rear two axles for on-road use, this reducing driveline stress and tire wear, increasing fuel efficiency.
