''The '''IMI 120 mm gun''' is an L44 smoothbore tank gun designed and produced by Israeli Military Industries (IMI). It is widely confused as a licensed production of the Rheinmetall L44 tank gun, however it was developed by IMI from 1983 to 1988, to meet the requirements of the Israel Defense Forces' Merkava Mark III main battle tank, i.e. a narrower mount like in the M-60, both tanks designed around a 105mm gun.''

Description

The 120 mm IMI MG251 is an Israeli-produced tank armament intended for their Merkava tanks.

Although sharing the same calibre and able to fire the same ammunition, the weapon is not a license-production variant of the 120 mm Rheinmetall L/44 cannon and is independently designed and produced in Israel.

Vehicles equipped with this weapon

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

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:

  • Possesses one of the highest-penetrating APFSDS round in the game with the M322, only beaten out by 120 L/55 ammunition

Cons:

  • M325 HEAT shell strength is mediocre at the fighting rank and is only useful against light-skinned ground and airborne targets
  • Reload time is akin to that of L/55 cannon, being much slower than 120 mm L/44 and 125 mm cannons

History

The 120 mm tank armament was developed by Israel Military Industries' (IMI) Slavin Land Systems Division.[1] It made its public reveal in 1989 as the main armament of the Merkava Mk.3.[2]

There are three known variants of the IMI's 120 mm cannon:[3]

  • MG251 - The first version mounted in Merkava Mk.3s
  • MG251-LR - An improved version that is mounted on Merkava Mk.4s
  • MG253 - A version with reduced recoil length, 40% less than the normal.[1] Used in the M60T "Sabra" in Turkish service.

The 120 mm guns are compliant with STANAG 4385, which means the cannons are compatible with other 120 mm NATO tank shells.[3]

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
