The Mark IV is the latest generation of the Merkava and has been in development since 1999. Its development was first announced in an October 1999 edition of the Bamachaneh (at The Camp) military publication.

[edit] Design features
The new model has a more robust fire-control system, the Knight Mark 4, produced by El-Op. The Mark IV has improved armor on all sides, including the top and underbelly, and is optimized for urban combat. The underside of the tank is reinforced with a modular, removable V-shaped "belly armor pack."
Ammunition is stored in individual fire-proof canisters, which reduce the chance of tank rounds cooking-off in the case of a fire inside the tank. As a result, the turret is classified as "dry", meaning that no active rounds are stored above the turret line.
Some features, such as hull shaping, exterior non-reflective paints, and shielding for engine heat plumes mixing with air particles to confuse enemy thermal imagers, were carried over from the IAI Lavi program of the Israeli Air Force to reduce the battlefield signature of the Merkava series tanks.
The Mark IV includes the larger 120 millimeter main gun of the previous versions but is capable of firing a wider variety of ammunition, including HEAT and sabot rounds like the APFSDS kinetic energy penetrator, using an electrical semi-automatic revolving magazine for 10 rounds. It also includes the incorporation of a much larger 12.7 mm machine gun for anti-vehicle operations (most commonly used against technicals)[11].

[edit] Upgraded fire control system
The new fire-control system enables the Merkava to operate as an anti-helicopter platform and is capable of detecting and destroying armored attack helicopters such as the French Gazelle and the ubiquitous Russian Mil Mi-24, both used by Israel's neighbors.

[edit] Upgraded tracks
The Mark IV has been designed with the Israeli-designed "TSAWS (Tracks, Springs, and Wheels System)" caterpillar tracks system, called "Mazkom" (Hebrew: מערכת זחלים קפיצים ומרכובים‎) by troops. This system is designed to endure the harsh basalt rock conditions of Lebanon and the Golan Heights with minimal "track-shedding."

[edit] Digital battlefield management system
A new and very sophisticated Israeli Elbit Systems BMS (Battle Management System; Hebrew: צי"ד) has been designed, constructed, and tested. It is a centralised system which displays battlefield data on color screens. It collects data from tracked units and UAVs deployed in theater, and immediately distributes it in encrypted form to all other tank units in a given theater.

[edit] Combat history
Controversy surrounds the Merkava Mark IV's performance during the 2006 Lebanon War, as a significant proportion of Israeli casualties have been among tank crews.[12] Hezbollah fired antitank missiles during the course of the conflict, penetrating armor in five Merkava Mark IV tanks and killing 10. The penetrations were caused by Hezbollah tandem warhead missiles, possibly including Russian-made RPG-29 'Vampir', AT-5 'Konkurs', AT-13 'Metis-M', and AT-14 'Kornet' missiles. Another tank crewman was killed when a Merkava Mark IV ran over an improvised explosive device (IED). This tank was equipped with additional V-shaped underside armor, limiting casualties to one of the seven soldiers (four crewmen and three infantrymen). Overall, 18 of the 52 damaged tanks were Merkava Mark IVs, eight of which remained serviceable on the battlefield. Two Merkava Mark IVs were completely destroyed, one by powerful IEDs, and another supposedly by an AT-14 'Kornet' missile. All but two Merkava Mark IV tanks damaged during the war were repaired and returned to the IDF. The Israeli military said that it was satisfied with the Merkava Mark IV's performance, and attributed problems to insufficient training before the war.[13][14]
After the 2006 war in Lebanon, and as the IDF becomes increasingly involved in unconventional and guerrilla warfare, the Merkava's role in the Israeli military has been questioned by some analysts who argue that the Merkava is too vulnerable to missiles.[15][16] Other post-war analysts, including David Eshel, disagree, arguing that reports of losses to Merkavas were overstated and that "summing up the performance of Merkava tanks, especially the latest version Merkava Mark IV, most tank crews agree that, in spite of the losses sustained and some major flaws in tactical conduct, the tank proved its mettle in its first high-saturation combat."[17] On a comparison done by the armor corps newsletter it was shown how the average number of crewmen killed per hit-and-penetrated tanks was reduced from 2 during the Yom Kippur War to 1.5 during the 1982 Lebanon War to 1 during the 2006 Lebanon War, thus proving how, even in face of the improvement in anti-tank weaponry, the Merkava Mark IV provides better protection to its crew. The IDF wants to increase orders of new Merkava Mark IV tanks, and has plans to add the Trophy active protection systems to Merkava Mark IV tanks, as well as increased joint training between crews and Israeli antitank soldiers.[18][19]

Challenger 2

FV4034 Challenger 2 is a main battle tank (MBT) currently in service with the armies of the United Kingdom and Oman. It is built by the British company Vickers Defence Systems (now part of BAE Systems Land and Armaments). The manufacturer advertises it as the world's most reliable main battle tank[2] As of January 2008, two Challenger 2s have been damaged in combat, and one destroyed by another Challenger 2 in a friendly fire incident.
Challenger 2 is an extensive redesign from Challenger 1, the MBT from which it was developed. It uses the basic hull and automotive parts of its predecessor but all else is new. Less than 5% of components are interchangeable. Challenger 2 has now replaced Challenger 1 in service with the British Army and is also used by the Royal Army of Oman. It has seen operational service in Bosnia, Kosovo and Iraq (2003–present). During the 2003 invasion of Iraq the Challenger 2 was the only tank operating in the Gulf that did not suffer a loss to enemy fire. In one engagement a Challenger took multiple hits from rocket propelled grenades and from one MILAN anti tank missile.[

Armament

A shooting Challenger 2
Challenger 2 is equipped with an 120 mm (4.724 inch) 55 calibre long L30A1 tank gun[5], the successor to the L11 gun used on Chieftain and Challenger 1. The gun is made from high strength electro-slag refining (ESR) steel with a chromium alloy lining and, like earlier British 120 mm guns, it is insulated by a thermal sleeve. It is fitted with a muzzle reference system, fume extractor and is controlled by an all-electric control and stabilization system. The turret has a rotation time of 9 seconds through 360 degrees.
Uniquely among NATO Main Battle Tank armament, the L30A1 is rifled, because the British Army continues to place a premium on the use of high explosive squash head (HESH) rounds in addition to APFSDS armour-piercing rounds. HESH rounds have a longer range (up to 8 kilometres (5.0 mi)) than APFSDS, and are more effective against buildings and thin-skinned vehicles.
Forty-nine main armament rounds are carried in the turret bustle; these are a mix of L27A1 APFSDS (also referred to as CHARM 3), L31 HESH and L34 white phosphorus smoke rounds, depending on the situation. As with earlier versions of the 120 mm gun, the propellant charges are loaded separately from the shell or KE projectile. A combustible case charge is used for the APFSDS rounds, a bag charge for the HESH and Smoke rounds. Contrary to speculation, this does not reduce the rate of fire of Challenger 2; in fact, a loader can often sustain a higher rate of fire than auto-loaders with single-piece ammunition. Separate charges reduce the likelihood of enemy fire igniting the ammunition.
The secondary armament consists of an L94A1 EX-34 7.62 mm chain gun fitted to the left of the main gun. A 7.62 mm L37A2 machine gun for anti-air defence is mounted in front of the loader's hatch. 4,200 rounds of 7.62mm ammunition are carried.

M1 Abrams

The M1 Abrams is a main battle tank produced in the United States. The M1 is named after General Creighton Abrams, former Army Chief of Staff and Commander of US military forces in Vietnam from 1968 to 1972. It is a well armed, heavily armored, and highly mobile tank designed for modern armored ground warfare.[3] Notable features of the M1 Abrams include the use of a powerful gas turbine engine, the adoption of sophisticated composite armor, and separate ammunition storage in a blow-out compartment for crew safety. It is one of the heaviest tanks in service, weighing in at close to 70 short tons.
The M1 Abrams entered U.S. service in 1980, replacing the 105 mm gun, full tracked M60 combat tank.[4] It did, however, serve for over a decade alongside the improved M60A3, which had entered service in 1978. Three main versions of the M1 Abrams have been deployed, the M1, M1A1, and M1A2, incorporating improved armament, protection and electronics. These improvements, as well as periodic upgrades to older tanks have allowed this long-serving vehicle to remain in front-line service. It is the principal combat tank of the United States Army and Marine Corps, and the armies of Egypt, Kuwait, Saudi Arabia, and as of 2007, Australia.

The main armament of the original model M1 was the M68A1 105 mm rifled tank gun firing a variety of high explosive anti-tank (HEAT), high explosive, white phosphorus and an anti-personnel (multiple flechette) round. This gun is a license-built version of the British Royal Ordnance L7 gun. While being a reliable weapon and widely used by many NATO nations, a cannon with lethality beyond the 3 kilometer range was needed to combat newer armor technologies. To attain that lethality, projectile diameter needed to be increased. The M68A1's performance in terms of accuracy and armor-piercing penetration is on par with the M256A1 up to 3000 meters out, but beyond that range the 105 mm projectile lacks the kinetic energy to defeat modern armor packages.
M256 smoothbore gun

A Marine M1A1 Abrams, 2nd Tank Battalion, fires its main gun into a building to provide suppressive counter fire against insurgents in Fallujah, Al Anbar Province, Iraq during Operation Al Fajr, 2004.
The main armament of the M1A1 and M1A2 is the M256A1 120 mm smoothbore gun, designed by Rheinmetall AG of Germany, manufactured under license in the United States by Watervliet Arsenal, New York. The M256A1 is a variant of the Rheinmetall 120 mm L/44 gun carried on the German Leopard 2 on all variants up to the Leopard 2A5. Leopard 2A6 replaced the L/44 barrel with a longer L/55.
The M256A1 fires a variety of rounds. The M829A2 was developed specifically to address the threats posed by a Soviet T-90 or T-80U tank equipped with kontakt-5 Explosive Reactive Armor. It also fires HEAT shaped charge rounds such as the M830, the latest version of which (M830A1) incorporates a sophisticated multi-mode electronic sensing fuse and more fragmentation which allows it to be used effectively against armored vehicles, personnel, and low-flying aircraft. The Abrams uses a manual loader, due to the belief that having a crewman reload the gun is faster and more reliable.[citation needed] Also important in the decision to use a crewman instead of an automatic loader during the XM-1 development was the fact that autoloaders do not allow for separate ammunition storage in the turret.[citation needed]
The new M1028 120 mm anti-personnel canister cartridge was brought into service early for use in the aftermath of the 2003 invasion of Iraq. It contains 1,098 3/8 inch tungsten balls which spread from the muzzle to produce a shotgun effect lethal out to 600 m. The tungsten balls can be used to clear enemy dismounts, break up hasty ambush sites in urban areas, clear defiles, stop infantry attacks and counter-attacks and support friendly infantry assaults by providing covering fire. The canister round is also a highly effective breaching round and can level cinder block walls and knock man-sized holes in reinforced concrete walls for infantry raids at distances up to 75 meters.[9]
In addition to this, the new XM1111 (Mid-Range-Munition Kinetic Energy) is also in development. Essentially a cannon-fired guided round, it has a range of roughly 12 km and uses a KE warhead which is rocket assisted in its final phase of flight. This is intended to be the best penetrator yet, an improvement over the US 3rd generation DU penetrator (estimated penetration 790 mm).
