The '''120 mm M256''' is an American tank cannon used in its top rank vehicles. It is most famously used by the American M1 Abrams series of tanks since its installation in the [[M1A1 Abrams]] model, though it has saw usage in older American tanks like the [[M60 AMBT|M60]] main battle tank.

Description

The 120 mm M256 is an American tank cannon used in its top rank vehicles. It is most famously used by the American M1 Abrams series of tanks since its installation in the M1A1 Abrams model, though it has saw usage in older American tanks like the M60 main battle tank.

It is based off the Rheinmetall L/44 cannon, though it is license-produced in America with a simplified design.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Pros:

  • M829, KE-W (on the M60 AMBT), M829A1 (on the M1A1 HC) and M829A2 (on the M1A2) are powerful shells
  • The M256 on the M1A2 Abrams has access to the high velocity, proximity-fused M830A1 HEAT-MP shell, enabling the M1A2 to engage helicopters and low flying aircraft
  • Reload is comparable to other NATO MBTs - 7.8 seconds stock and 6 seconds with an aced crew
  • Relatively wide selection of shells - M829 and M830 on the M1A1, M829, M829A1, M830 and M830A1 on the M1A1 HC, M829, M829A2, M830 and M830A1 on the M1A2 Abrams. The M60 AMBT gets access to the powerful KE-W APFSDS shell (which is a tungsten based M829A1 shell, without the depleted uranium tip) and the M830 HEATFS shell
  • M830A1 is a fast HEATFS shell with a muzzle velocity of 1,400 m/s
  • Extremely high muzzle velocity on M829, KE-W, M829A1 and M829A2 makes longe range sniping a satisfying experience
  • Great gun handling characteristics - the gun elevates towards +20 and depresses towards -10 very quickly
  • Very effective stabiliser - does not stop working at high speeds

Cons:

  • Poor stock grind - enemy tanks are very capable of withstanding M830 HEAT-FS
  • M830A1 is not effective against enemy MBTs - it only has 350 mm of chemical-based penetration
  • The M256 on the M1A1 Abrams and M60 AMBT do not get access to the M829A1 APFSDS shell and the M830A1 HEAT-MP shell
  • M830A1 needs to travel a certain distance to arm the fuse - unable to engage helicopters at close range, except for a direct hit

An aced Challenger 2 and Challenger 2 (2F) can beat you by a full second, the Type 90 and Type 90 (B) (due to their autoloader) by a full 2 or 3 seconds, depending on your crewskill
  • M830A1 self-destructs at 4.5 kilometres - helicopters can engage the M1A2 way beyond that range
  • M830A1 requires a direct hit for maximum effectiveness - near hits result in little to no damage to the enemy target

History

In 1972, as the replacement to the cancelled MBT-70 and XM-803 was beginning development by Chrysler and GM, a 120 mm smoothbore gun had been considered. However, the developing gun by West Germany was not expected to be produced in time to meet the scheduled production timeline, and so the 105 mm M68 was retained as the main armament for the upcoming design.[1] In 1976, during the decision on which company will receive the contract to produce the XM-1 tank, a separate decision was made for the tank to be able to accommodate a 120 mm gun in the future, either the British 120 mm rifled gun or the German smoothbore gun. On October 28th, the XM-1 designs were modified with this new requirement.[2] Chrysler eventually won the contract to produce the tanks, but they were armed with the 105 mm M68A1.

The German Rheinmetall 120 mm was eventually chosen to become the next tank armament for US tanks. Receiving a license to produce it, the Watervliet Arsenal produced the Rheinmetall cannon as the M256.[3] With the original Rheinmetall design considered overly complex and expensive, the M256 had been redesigned with fewer parts.[4]
