Pros and cons

Pros:

• High-penetration APFSDS round

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

An Israeli Merkava Mk.3D from the 188th Armored Brigade fires off a shot from its 120 mm.

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

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

• 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. 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.
